I think a closer analogy would be poker. With craps and roulette you're at the mercy of the house and aren't in any control. Poker you're playing against other people and make your own decisions based on the cards you hold and ultimately it's your fault you won/lost. Either way it's a good analogy, any friends and family giving you money need to know that they won't see it again for a long time, if ever.
