ONLY MY OPINION---

I firmly believe in to 80-20 rule (which you see in all sorts of situations), although I doubt the winners of much substance would amount much more than around 12%...

My poker tracker database has been consistantly about 1/3 winners. However I also know that a lot of that is based on when they play at my table. One large suck out with 9 10 suited against AA in an all in makes them a WINNER but probably not in the long run. The person who has won the most money off my played me 4 hands and won a $67 all in with me when he hit runner runner flush against my set of A's. I've lost almost $300 this month (Not a good month) yet I'm winning over the long haul. For me i've got over 10K in hands most other people I've maybe got several hundred hands.

Think of all the people that play & then quit when they lose their deposit, then never play again. Gotta be alot over a course of a year. 1 thing almost every successful poker player have in common is a period of extreme luck when 1st starting. I think that is generally needed to get them through their first losing streak. I know I had it or I doubt I would have kept playing.

I suspect if you put a qualifier, such as only looking at players that continued to play over the course of the entire year it would be closer to 50/50.
