Gambling is entertaining and there's always a money involved. You cannot make gambling for investment because based on my experience you will always lose.
Ya like you said,when we thinking gambling as only for entertaining for spending our freet time,we will got some profit.But if we think gambling seriously,we surely will get busted in long run.
hahaha everytime we seriously played the game we got busted because of this emotion that we cant control but like you both said if just playing completely for fun winning can be possible just don't take it personally. good luck
