Do all PGA pros teach the same if you are new?

Yes, it does highlight the fundamental mistake even the adult beginner makes and why golf is so difficult to learn - actively using the wrists to try to flick the ball, more like a table tennis hit. Kids do it even more so, usually with a quick forward lift of the clubhead by forward bend of the right wrist.
Learning that the golf swing is really a body motion that causes the arms and clubhead to swing, not an arms and wrist driven action is the crucial learning to get to grips with golf. You wont show a three year old, but youth or adult beginners should be shown one of the trebuchet analogies to understand as quickly as possible this key counterintuitive action in golf.
