Technically, if someone wins in gambling of course they will be happy, satisfied, grateful and etc. You might also get full of yourself then you'll tend to play again and try to win again which is nearly impossible to happen. In my experience in this industry, I never been win once especially in online gambling which make me sad and leave gambling. I never regret that lose because I realize that this isn't the way for me, this isn't the path i want to take so I leave.
Even once?😢
You need to try different games like dice which is just depends on your luck so you may win few times and getmyourself satisfied from that myth.
As a gambler I understand it's really hard to win. You have more losses than win but even how hard to win or unlucky you are, it's nearly impossible someone saying he didn't win even once. There's also what gamblers called beginners luck.
