His point is it doesn't matter much if you hear that advice you still need to spend hundreds of hours improving your mechanics to actually execute that advice.
And my point is that there are many things beginners should and could do that they do not know about. Yes of course, once you have the advice you need to train and not everything is actionable. But for beginners something like a build order is actionable, and if you don't know about them, inventing them by yourself is going to take a while.
