That's why you always have to make sure that your spendings are in check, otherwise even if you win against the casino, your greediness will lead you to lose it all just because you haven't stopped when you're ahead. The high % of wins on the side of the player, on paper, might seem like a good deal. But in reality it's really in favor of the casino because that less than 1% will always eat out the winnings of gamblers in the long run. You can never really disregard those small percentages because that's what's going to bite you in the end.
