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.
