I think that teaching a skill and it being taken up easily is fine. It's like if a parent is a rock climber, they  can teach their child to rock climb at an early age and they will become better at it earlier than the parent did. It's like evolution. But that only covers the kids. Vegeta's passion to be better than Goku helped him obtain it, so i think all the reasons so far have been legit.

Maybe not Cabba learning it in 5 minutes.
