"All bets are off" is an expression used when a situation changes dramatically and nothing is certain anymore. It is often used when predicting an outcome that may have seemed likely, but something unexpected has occurred that changes the situation. For example, if you were to predict a sports team to win a game, but their star player gets injured just before the game, you could use the expression "all bets are off" to indicate that you no longer think the outcome is certain. Simply put, "all bets are off" means that previous assumptions or predictions are no longer valid due to unforeseen circumstances.
