No gambler treated gambling as entertainment all the time he is playing, there will always be a time of changing or shifting your mindset, we are tempted to be like that, we are just humans and tempted to be greedy especially when money is involved.
It's mean your self control skill is bad and you need to think what's the reason your mindset is changed. I was a gambler who gamble for money, but mostly I didn't achieve my goal and I'm not happy with the result. After that I learn to change my mindset to gamble only for entertain, regardless of the outcome is, I always happy since gambling is fun. Until now my mindset is never changed and gamble is always to entertain for me.
You are right, but I still will agree with what coin-investor said , he is actually right, I myself I gamble mostly for entertainment, but if we must be honest with each other, we all will have to agree that any gambler who claims to gamble for entertainment all the time is liar and living in self denia.
In as much as gambling is solely a recreational way of having fun or one entertaining him or her self, as long as it is possible to win money in the process of entertaining oneself, there will always be times when the gambler will be tempted to focus on making some money rather than pay attention to the entertainment part, this is just normal with every human, there is no need saying otherwise.
