Ask yourself this:
Would you be happy repeatedly flipping a coin with an opponent to gamble?
That is exactly 50/50
Would that be better or worse than what you do now?
I don't think that works. People may say whatever they want, but the main reason people gamble, and that is well reported in psychological and sociological studies, is the illusion of controlling an unexpected event, and the pleasure that comes from that. Of course that there are many other variables, but that is base behind gambling success. You go to a casino or talk to a gambler, or even look the the threads on this forum, and you will see people discussing strategies for gambling, when everyone knows but prefer to ignore that there is something called house edge, and you are expected to lose in the long run, and although you can win in the short run because you are lucky, it will definitely not because of your amazing strategy.
So if you put something like the flip of a coin, the margin or illusion is smaller, it will be harder to convince yourself that you have a strategy to win and control the flip of a coin. Although even there you will see people discussing martingale and other betting strategies.
So flipping a coin, playing roulette or craps or dice or whatever, will be the same, but it will feel worse because it's harder to fool yourself on such a simple game.
(I exclude poker and sports betting, because there is strategy involved there, although the base is the same, trying to control the unexpected, but you do have a small chance of doing that, but luck still plays a large role even in these games)
