If a player in my team got an attribute boost and PA boost in the winter update will my player get it too when I install the update?

If a player gets boosts in the new version of a game which I dont purchase, will the player get a boost in my version of the game?

Any data changes will be implemented automatically if and when you install the latest game update.  This will only be relevant to the game that is being updated.

If you're asking whether your players in an active save will be affected by data changes, the answer is no.
