Rey isn’t a Jedi yet.
Which begs the question what does Rey miss, that would prevent her from being called a Jedi? She has pretty much all the skills, and clearly has an unprecedented level of control. She defeated Kylo Ren, resisted Snoke, and rejected Kylo Ren’s offer. What else is left for her to do, outside of defeating Kylo Ren again? I’m sure she could learn a whole lot more, but then again so did Luke at the end of ROTJ.
