Gambling is made to have that kind of fun, but we all took it wrongly and aimed to make money out it and at the end we don't enjoy the games and also end up losing money. If you want to enjoy the games then you shouldn't worry much about the results then only it is possible.
Yes fun is the only possibility we could get from gambling but unfortunately we are not at all aiming that from gambling.
It is human nature, we are all not welcoming what is easy available to us and struggling what is not at all achieveable from gambling. I guess it is a general human mentality and that is the reason we are facing many problems from gambling, yes all due to an incorrect aim with gambling.
