That is accurate but not all of the people who go to casinos and gambling places are aiming to win good amount of money, some of them just want to have some fun. There are some people who go to casinos out of frustration at job, being exhausted on job and wants to breath on the air of fun and enjoyment.
All of us would be happy to have profits in gambling, seeking for fun in playing gambling are only for those people who are bored and don't know what to do with their money, so they are happy wasting it or whatever they want to it. I remember it when I was still playing gambling, I won 0.5 bitcoin out of my 0.04 capital, I'm so happy that I didn't notice that I'm losing, all what I did was to keep on betting.
