If someone made Ave. annual profit of 10% from trading in the last 20 years, is he considered good?

I know it might be a silly question but if you have to guess, what would be the annual average earning(before taxes) in the last 20 years from "combination of short term and long term" stock trading be for a "top 1%" stock investor? And what would that be for the "top 10%" stock investor? And then for the average Joe investor?
