What makes you think they are two kinds of people?? You're making a big generalization here. Both play for money, "gamblers" often bet other things besides pool, horses, cards, sports, golf, chess, backgammon, etc. Gamblers, by my definition, will bet just about anything, sometimes even taking the worst of it. There are all kinds of nits who will only play people they can beat, even at things besides pool. The way I see it, gamblers put their money in action and concentrate on it from dawn to dusk. But, I'm not talking about "problem gamblers", either. They absolutely have to bet on something, all the time. The guy who makes his living gambling, and I have known a few, is a different animal. I'm not sure I understand the term "money players" as you have used it.
