First, you didn’t actually learned those things, you trusted them. Second, im not speaking about trivial common knowledge. There’s obviously always something useful to learn from theory in any area.

But its subtle things that make all the difference between average and really good in something, these ones you can’t really learn without gettyhands dirty and making own mistakes. Even though often it seems different looking backwards, but it’s nothing more than a curse if knowledge.

I strongly agree here. It was the subtle things about breath control and muscle-tension control were what I learned while practicing marksmanship.

It is simultaneously true that a person starting out can sometimes see they need guidance to learn the 'trivial common knowledge' that others in a field are already familiar with. These things that seem 'trivial' to experts are things that help them avoid the "many ways to fail at getting good at something while doing it a lot."
