Baby's position at anatomy scan

FTM. Had my son's anatomy scan at 21w2d and to my surprise, he was already head-down. Seems like most people's babies are still "breeched" at this point. Anyone else had their baby head-down this early? I know babies usually don't get into their final position until like 32 weeks so does this mean my son is more likely to be breeched since he's head down at 21 weeks with a lot of time yet to move?
