There is a difference between a poker player taking a gamble and a gambler playing poker. Yes, we sit at a table and hope to get dealt pokcet aces. That's counting on luck, that's gambling.
But, while there are similarities between poker players and gamblers playing poker, the differences are greater. Take the pocket aces. I think the gambler wants to get his money in preflop and leave it to luck to decide who takes a big pot. The poker player wants to make intelligent decisions on how to proceed with his aces. She wants to make a reasoned decision on what amount to bet to get 2-3 callers, see the flop, and make another reasoned decision on how to proceed from there.
Some people don't understand why anyone would ever want to lose a hand. Like Doyle says in the introduction to Poker After Dark, poker is a game of making the right decisions. If you have made the right decisions, and got your money in with the best hand, then you have played the game as well as it can be played. And sometimes you get sucked out anyway. But you played the best. You were proven to be the most skillful. And, if you are the most skillful, in the long run, you'll win - even if you lose a few hands along the way.
