Rey has been training on flight simulators for years and piloting other ships in the background, PS 7 maybe
Force sensitivity and the precognitive reflexes it gives is an amazing buff to your piloting ability. Luke managed to survive the Battle of Yavin and being attacked by Vader. His piloting experience? A beaten up T-16 Skyhopper. When it's incredibly high Force Sensitivity like Rey or a Skywalker PS8's to be expected.
It makes Han, Dengar, Wedge, Soontir and Talonbane all that more impressive for being PS9 without it.
Wedge was also force sensitive according to the old cannon. Even the old decipher card game (from where the names of the tie fighter pilots in this game come from and that before disney was considered a cannon source ) presented him as same force level as luke.
