Yeah may it could be happened. Can you please tell me What does House edge exactly mean? and how is it work?
house edge is a ratio of the loss that a gambling site expected from your initial bet
in short 1 % house edge means that for every bet you make there will be 1 % loss from your initial bet in average. If you are to visit a dice sites that has 1 % house edge you can see that for 50 % chance to win, you will get just 1.98x of your bet instead of 2x of your bet.
