      Consider a casino. You are sitting on one side of the blackjack table,and the dealer (the house) is on the other side of the table. Both you andthe dealer are playing the same game, so is it true that you are bothgambling? Yes and no. The yes part is obvious. The no part is somewhatsubtler. Because the house has a statistical advantage over you, it willmake money over time. While it is possible to win at blackjack, over timethe average gambler will lose money. Gamblers that count cards can turn theodds in their favor, giving them a statistical advantage over the house.That's why casinos ask card counters to leave and kindly never return.
