For me playing in the demo version is quite fun for the beginning of the game but the fun only lasts a few minutes and after that it's boring, on the other hand of course as I said before friends that there are no real wins and real losses in free mode, all that is just a picture that we can see and without us feeling the results if we win so that's what makes most gamblers not put any interest there, some may switch and play in free mode when they run out of money but most people prefer to find money or loans to return to playing in real mode. Agree with you that most gamblers may make gambling as a place of income even though the reality is far from what they always think and expect, the fact is that it is very difficult to get a winning streak there, simply put you will experience 1 win at the expense of 3 - 5 defeats, that's a fact.
Yes, it is true. in fact, gamblers in the name of fun or hobbies are just lies. basically, they want to get more money from gambling winnings, or even some just want to return their lost money. but it is very difficult to return it and, in the end it will only add defeat.
This is too wide a generalization, if what you said was true and no one was willing to use any money to entertain themselves then we will not have movies, video games or any other activity which is done for the sole purpose of obtaining some fun with it.
However the evidence shows the demand for those industries does nothing but to go up, so it stands to reason that there are many persons that gamble just for the entertainment they can get out of the games offered by casinos.
