Of course it is.
Is it that people are just pretending to be gambling for fun meanwhile everybody (all gamblere) are actually gambling for financial gains.
The possibility of winning money is the essential component of the fun, what makes it exciting.
I had a friend that gambles only during the weekends, he claimed to gamble for fun only but In two weeks he was losing more than 300 dollars, and I asked him if he an addicted gambler but he denied it. Most gamblers are just afraid to admit that they are actually addicted <...>
Well, that's another thing. An addict will deny being one. Therefore, they'll use any excuse, like in this case.
