Also, it's not that difficult to play dice
Jesus Christ
You're right man, I think

That's right. If all were losing all the time, and only this way gambling sites could be making profits, gambling would cease existing long time ago.
Man, you're wrong. Gambling it's not about "losing/winning" this is about thrilling and risk. Human need something to thrill about. This is from where gambling appeared.
So if gambling would not create such moments for us, only in that case it would disappear long time ago.
