i think kylo ren is right. her parents are force sensitive nobodys untrained in the force. they left her on Jakku on purpose through the will of the force. the force led her to be talented in the technical field for a living. i still think Rey has unknowingly been training shatterpoint.
I think that Kylo Ren is telling the truth from a certain point of view: namely, his own. I can, however, think of quite a few people he'd think of as "nobodies" that almost everyone else in the galaxy would disagree with him on, because he's just that much of an edgelord.
