The property Users does not exist on object<App\Controller\Admin\AdminController>. Since you implemented __get, maybe consider adding a @property annotation.

                $this->eventManager()->attach(new Statistics());

The method Cake\Event\EventManager::attach() has been deprecated with message: 3.0.0 Use on() instead.

new \App\Event\Statistics() is of type object<App\Event\Statistics>, but the function expects a callable.

                $event = new Event($event);

Consider using a different name than the imported variable $event, or did you forget to import by reference?

                $this->eventManager()->dispatch($event);

                return $event->result;
            }, 'statistics');
