For every win, there is an equal possibility of losing everything. I am not a lover of casino games, but they appear to be the quickest, particularly poker with jackpots. The win instances are once in a blue moon, but if luck is on your side, you may become a millionaire with a jackpot, but as I previously stated, the likelihood of winning the jackpot is very slim, and you will most likely lose everything you have wagered.
This is why I enjoy sportsbooks, my predictions are my skills, and they are what I rely on, a little win is far better than several wagers that may not yield anything, sometimes you just need to curb your greed in gambling, it is not how large you win, but how accurate you are in all of your outcomes.
