It was an incredible session, thanks for the feedback. I don't want to ruin your comment but the very next roll would have been random so manybe not 99.x if he kept betting at 1% since he would not have clicked exactly at the same time and since it would be a different univers so a random result 
Breaking Headline!
Provably fair crypto dice game refutes the quantum uncertainty principle!
On a serious note, there is nothing "random" about the roll. The nonce, and thus hash, and thus roll, would have been the same regardless of the timing of the "click". There is no actively accumulated entropy in the "rng".
Poor BAC, can't get a break recently
