Do folks generally still believe that the "masters" are/were born great, rather than being born with an advantage of some sort (whether by nature or environment) and then leveraging that to achieve mastery of some craft?
I don't know about born "great" but born with a different perspective seems reasonable. The perspective maybe nurtured by the environment. I think the environment could be a repetitive task or plenty of leisure time.
I believe luck with timing is the biggest determination.
