I think the odds of winning a jackpot in a casino depend on various factors such as the type of game, the number of players, and the specific rules and conditions of the casino. In general, large jackpots may have lower odds of being won due to a higher amount of money involved and more people participating in the game. However, it's important to note that the odds of winning any game in a casino are typically low, regardless of the size of the potential payout.
