But the pot does what it is supposed to do - that is draw a crowd big enough to make sure the casino milks them several multiple times of the amount in the pot, such that in case in future someone wins the pot, the casino is still in a new profit.
I agree, in general casino always win against players, it is by design. People get an entertainment for their bids, it is comparable to buying a ticket to some performance. Fluctuations from the pattern (those who actually win) does not change overall picture.
