I doubt there is a single one of us here that enjoy losing bets or money right ? if you do , I think you have some problems or you're mega rich and you don't care about money but 99% of gamblers really don't enjoy when they lose money as most of them are gambling to become rich and they are afraid to admit it and that is the first sign of addiction. For me , when I have a losing streak , I stop betting and maybe after 2-3 weeks I will try another random bet to see if I'm still in the same situation or my inspiration and luck are back. 
The thing is that gambling is a random event.
Every single game is independent of the previous ones. That means that you can wait a week, month or a minute, and the probability will be the same in the next game.
There was a time in the past where games were "easier", for example roulette tables didn't have the double zero, making it more probable to win compared to current ones.
