This is true, based on what I noticed gamblers will tend to bet more once they won without really thinking that his win isn't equal to his losses if really calculate it, gamblers cannot actually see that for the fact that they don't calculate it and losses doesn't really matter after they win, all they think about is they won. Success in gambling is very low considering that gambling sites have house edges and gambling should not be an option in desperate times because it'll just make it worse.
