Is Freebitco.in dice game really probably fair. As I lost some big amount at even 1.01 odds back to back 3 times. I would have betted approx 15 times in odds of only 1.01 and I lost 3 of those

and this makes me think this.
1.01 is one is a hundred probability and lossing 3 times out of 15 really made me think this. Can any one tell me about it how does this really work.
Odds are just probability, the results are not guaranteed based on the odds. Freebitco have 5% house edge, 1.01× payout mean 94.06% win chance. So, you have 5.94% chance of losing your bets. Don't be surprised with your 3 losing streak in 15 bets. I think you are ignoring the fact of house edge. Losing streak depends on the combination of HE and bet payout.
Yes results are not guaranteed but I was not expecting to loose those bets, that was the reason I Betted only in 1.01x payout odds so that I can minimise my chance of loosing even if I win very less but that I think back fired.
Yes housing edge I ignore, so there would be 5% chance of loosing always minimum even if i bet at an odd of 1. Well it was a bad day for me today I would consider.
