"Plenty" is kind of vague. How many in total are we talking? 100? 1000? 10k?
Well, how many artists are there in total?
Hundreds of millions. Up to a billion maybe? If you mean people that actually make a living at it, not many.
Art is highly valued it's just a winner takes most market just like sports. A tiny minority make all the money and the rest get nothing.
This seems both a) vague and b) based on a sample size of n=1. 85% of all visual artists in the U. S. make less than 25k/year [0]. Also, don't forget that most artists work in companies (again: visual art), like making story boards for anime etc.
