Remember Force powers are nothing more than wish fulfillment, the training is mostly about control and finding out what you can actually do. Luke had all of like 10 minutes of Force training before winding up in an X-Wing and flying better than almost everybody else. And as for lightsaber, she really wasn’t that good, it was just that Ren was fighting a subduing style, big slow hard swings to tire the other person out, because he didn’t want to kill her. Anybody can fight against that, you’re SUPPOSED to be able to block all the shots. It’s not like she did any double moves, that’s where things get hard.
Like was a amateur pilot that had actual prospects of going to the Academy, that’s why he was decent. Not the force.
