If you bet $5 on each hand and were paid $15000 that would be the correct payout. The $25000 you mention may be the table max payout for any one hand. If you had $25 bets you would still only get the max of $25000 not the $75000 ou expected. Always make sure to never bet so that the expected win would be more than the table max or you are just contributing to the house.
