Many users claim that they play for fun. At the same time, they do not hide the fact that all the money is lost one way or another, quickly or slowly. If you are losing money, then how can you enjoy it?
While playing and there may be gamblers unknowingly experiencing the thrill of free spins and the results are far from expected.
If you lose and the money runs out, then the phrase about gambling for fun cannot be interpreted in the way you mean.
It could be that the gambler came to play already knowing that he would lose his money and throughout the game he was entertained by the fun he had during the game.
For me, the answer is the same as going to a club to party, even if the person leaves the room drunk.
