(Couldn't find a good search string for this topic, I'm sure its been discussed.)

Every poker player I know tells me that they make a profit in the long run, yet I don't, but these same players turn to me for poker advice (live home games) thinking I'm the best player in the group (an image I let them keep of me). But its obvious they can't ALL be making money.

On top of that, I know very few people personally who profit online. Pretty much everyone I know says they win live and lose online. Although I am a winner at $10NL over 9k hands ($60!!! yess!!!).

Anyway I don't care about my own winrate I just didn't want the replies to be about me losing or whining. My question is simply How many/What percent of poker players actually win in the long run? Is there a huge difference between online and live? Is it the top 10% of players? Top 20%? Educated guesses or links to previous discussions are fine :P
