Anybody saying gambling is for fun and not for making profit must be keeding. Just as you said if gambling where to be fun nobody would risk his money on betting why they can equally watch thesame game without the intention of making money. I believe that gambling is for making money. though there might be fun, but the fun in it does not justify that profit is not the primary motive. Whenever you think of gambling, you think of wealth and how to quickly achieve it withing the shortest period of time. For me gambling is for making money and not for fun.
I think what you misunderstand its the term "for fun" there. It clearly stipulates non expectation in gambling. When you engage in something without serious expectation from it, its as good as catching cruise with that stuff with limited emotions attached to it. That's the mentality gambling should be approached with. Catch your cruise with gambling and never allow gambling catch cruise with you. It helps you to gamble in moderation
Emotiinal attachment tho gambling brings addiction, big loses, unnecessary pressure of recovery and depression when the losses are much. Don't approach gambling with a money making mindset, always gamble for fun and you're good to go.
