you need to use @FXML only to call nodes (with an id) inside the fxml.
stage contains your fxml, so delete these lines.

# 2 #
your fxml is supposed to be added in a scene. it knows nothing about it before his initialization.
it means that your code is "garbage"... (sorry)
make it in this way:
create a class like this that will create the scene and will fill it by the fxml content:

public class ClassName extends Application {
            
    public static void main(String[] args) {
        Application.launch(ClassName.class, args);
    }
    
    @Override
    public void start(final Stage stage) throws Exception {
        //use here the path for the fxml you want to load as root
        Parent root = FXMLLoader.load(getClass().getResource("fxmlPath"));

        final Scene scene = new Scene(root);  

        stage.setScene(scene);
        stage.setTitle("Title");

        stage.show();
    }
}

then in fxml controller, just write nodes parameters, listener, handler etc etc related to the fxml itself.

ask for more or look at the javafx tutorial
