For professional low level poker players, a good deal of their income comes from rakeback. That is, for every hand, the site makes $N (the "rake"), and the player gets back X% of N/players, where X scales according to the amount of volume put in. I'm a bit out of the loop but you can assume that N is around $3 and X is probably in the 35% range. Some people semi-derisively refer to these people as "rakeback pros", in that you can break even (or even lose a little bit) in your poker results, and still make a living wage from the rakeback alone. Also, 387k hands probably takes less time to play than you think. Many online grinders play upwards of 1000 hands/hr - 20+ tables concurrently X 50-150 hands/hr.
