Actually I've lost a large amount on gambling. I often spend some bitcoin which I deposited in gambling. But I gamble just to play, because I like to play like poker, sports betting and blackjack. It was very nice to me, and most importantly, a good self-control in order to avoid the greed that can result in huge losses.
I also spend quiet regualarily my bitcoins in the gambling specially on sports betting and its a mixture of loss and win for me but talking about overall,yes i am in loss also,because of the odds are such,then in a long term no one can end up in the profit.
