I think deviations can affect casino affairs. Deviations or variances are part of statistical probability, and casinos are heavily reliant on probability and statistics to make profits. However, any large deviation from the expected outcome can lead to a loss of profits for the casino. For example, if a player wins an unusually large amount of money, it can affect the overall profits of the casino. Similarly, if a particular game or slot machine is experiencing a deviation from the expected payout percentage, it can impact the casino's bottom line.
