I think both are true. With training we reinforce our method and knowledge - whether good or bad. But even choosing a bad method you still get better but maybe hit diminishing returns faster. A good method lets you get better in a more sustainable way and avoid hurting yourself. E.g. when an art teacher tells you to draw from your shoulder instead of fingers, wrist and elbow as almost everyone is used to. In the beginning you probably get worse and frustrated, but down the line it makes a ton of a difference having to ability to do so even if not needed for everything.
