Query with empty results laravel eloquent

I´m traying to create statistics from my database. I´m changing application and before statistics was created from call table. But i change this and i was created a new table statistics and have this column:

id, id_ployed, call_id, created_at(nullable), updated_at(nullable)

and data example for example:

52,60,88988,4
53,60,88989,10
54,60,88990,6
62,9,88999,1

i have this function in my controller, but return empty data and it´s imposible:

$estadosLlamadas = EstadoLlamada::orderBy('desc')->get();

        if(isset($request->fromDate) && isset($request->toDate)){
            $fromDate = Carbon::parse($request->get('fromDate'));
            $toDate = Carbon::parse($request->get('toDate'));

            $fromDate = $fromDate->format('Y-m-d');
            $toDate = $toDate->format('Y-m-d');

        }else{
            $fromDate = new Carbon('first day of this month');
            $toDate = new Carbon('last day of this month');

            $fromDate = $fromDate->format('Y-m-d');
            $toDate = $toDate->format('Y-m-d');
        }

        $teleoperadoras = auth()->user()->whereIs('teleoperadora')->activos()->select(['id', 'nombre'])->orderBy('nombre', 'desc')->get();
        
        $array = [
            'toDate'   => $toDate,
            'fromDate' => $fromDate,
            'nombresEstados' => $estadosLlamadas->pluck('desc')->toArray(),
            'coloresEstados' => $estadosLlamadas->pluck('hex')->toArray()
        ];

        $query = Estadisticas::query()
            ->whereDate('estadisticas.created_at', '<=', $toDate)
            ->whereDate('estadisticas.created_at', '>=', $fromDate)
            ->whereIn('estadisticas.id_empleado', $teleoperadoras->pluck('id'))
            ->join('users', 'estadisticas.id_empleado', '=', 'users.id')->latest('estadisticas.updated_at')->get();


        foreach($teleoperadoras as $teleoperadora) {
            $array['teleoperadoras'][] = $teleoperadora->nombre;
            $array['id_teleoperadoras'][] = $teleoperadora->id;
            $array[$teleoperadora->id]['resultados'] = [];
            $array['llamadas'][] = $query->where('id_empleado', $teleoperadora->id)->count();

            $array['llamadasTodo'][$teleoperadora->id] = $query->where('id_empleado', $teleoperadora->id);

            foreach($estadosLlamadas as $estado) {
                $array[$teleoperadora->id]['resultados'][] = $query->where('id_empleado', $teleoperadora->id)
                                                            ->where('id_estado', $estado->id)->count();
            }
        }

        $array['nllamadas'] = $query->count();
        $array['fromDate'] = $fromDate . " 00:00:00";
        $array['toDate'] = $toDate . " 23:59:59";
        $roleUser = auth()->user()->getRoles()->first();

        return [
            'datos' => $array, 'estados' => $estadosLlamadas,
            'teleoperadoras' => $teleoperadoras, 'roleUser' => $roleUser,
        ];

this fill statics with chartJS:

$.ajax({
            type: 'GET',
            url: "",
            data: { 'fromDate': fromDate, 'toDate': toDate },
            success: function(response){
                console.log(response);

                $("#loadMe").modal('hide');

                var totalCall = 0;
                let totalCallByOperator = response["datos"]["llamadas"];

                $("#totalCall").append(response.datos.nllamadas)

                // append all teleoperator in view with calls number
                response["datos"]["teleoperadoras"].forEach(function(teleoperadora, index) {
                    $("#teleoperadoras").append('<b class="teleoperadora">'+teleoperadora + ": " + totalCallByOperator[index] +'</b> <br>');
                });

                // generate general statistics
                var ctx = document.getElementById('canvas1').getContext('2d');

                var myChart = new Chart(ctx, {
                    type: 'bar',

My model its:

class Estadisticas extends Model
{
    protected $table = 'estadisticas';

    protected $primarykey = 'id';

    public $timestamps = false;

    protected $fillable = [
        'id_empleado', 'id_llamada', 'id_estado', 'created_at', 'updated_at'
    ];


    public function teleoperadora()
    {
        return $this->hasOne('App\User', 'id', 'id_empleado')->withDefault();
    }

    public function estado()
    {
        return $this->hasOne('App\EstadoLlamada', 'id', 'id_estado');
    }   
}
