Certainly more common than Michelangelo-level artists! I think the OP's point was that you don't need to be the absolute best in your field, or even that close, to be rewarded handsomely.

There are artist all over instagram that can do anatomy better than Michelangelo. In fact Michelangelo never painted a portrait because he couldn't do it. Leonardo could but Leonardo could not sculpt.

Agreed. And this makes not even being close even harder for me.
