I don't think there really are that many that win enough to make a living from it. Just about everyone of these guys does a bunch of shit on the side, like write articles for magazines, have some online expert advice site, hope to hook up with one of the big poker sites and wear patch for money. Even Jen Harmon of on some TV show doing a Vegas living thing.
If they win so much money playing poker why do they have to do all this other stuff?
Then you go look at these so called Pro poker players results at the WSOP events and 99% of them are down and down a sizable amount.
