You obviously don't read much poker literature. I am not even close to being a pro, but I read a lot. What I read generally says if you want to be a pro (not including living expenses) you require 100 buy ins (this will carry you through the lean times), So if you are playing $1 $2 cash games with a buy in of $200, many pros recommend 100 buy ins. So you would require $20,000 just for buy ins. I am sure some players do it with less but many pros will state otherwise. Like I said, this does not include living expenses. In my country $500 would be considered ultra poverty. Try living in a cold country like that, Here in Canada it's usually called homeless!
