There’s something special about Rey. Since it’s highly unlikely that it’s a case of famous parents, the other obvious explanation is that the Force was awakened in her for some purpose, and I think it’s logical to conclude that it’s for the purpose of finding Luke due to her proximity to the Falcon and so forth.
I don’t think that just anyone can be a Jedi, you have to have a special talent for it. But to some extent, everyone in this universe can be attuned to the Force. The Force controls a person’s actions, but very few manage to get the Force to obey their commands.
