呼叫：

public function statisticsNum()
    {
        //報名數量
        $bao_data = RonPositionLog::groupBy('user_id')->select('user_id as id', DB::raw('count(position_id) as bao_num'))->get()->toArray();
        app(RonUser::class)->updateBatch($bao_data);

        //收藏數
        $follow_data = RonCollection::groupBy('user_id')->select('user_id as id', DB::raw('count(position_id) as follow_num'))->get()->toArray();
        app(RonUser::class)->updateBatch($follow_data);

        //我的下級數
        $tui_data = RonUser::where('agent_id', '<>', 0)->groupBy('agent_id')->select('agent_id as id', DB::raw('count(id) as tui_num'))->get()->toArray();
        app(RonUser::class)->updateBatch($tui_data);
