I had some interesting wins around $2k - $2.5k but unfortunately I have never had such spectacular wins.
It's hard to believe that you can win millions if you risk a few dozen cents or a few dollars. But I think this statistic is not about the total amount someone risked, but about the one-time bet that brought him that win. In fact, theoretically, these people could have played for years and lost in the past a much larger amount than they won
