Could also call it inevitable on one factor which is if the person betting has consistency in their good judgement when betting.  If they really have the skills it would mean they certainly compound gains into gigantic amounts, only a few people in a million are capable of such a thing.   But if someone has good judgement and doesnt bet it all, regularly takes profits they will get this high.   
  There have been a few famous people who did as much, sometimes they later on lose it all chasing the thrill and taking too much risk but some people have the inside edge in how they bet.
