When the experts says the gambling is a game of chance, then no one is sure of winning even a single game and mostly you on the side of losing. In a gamblingm even those who bragged themselves as masters of gambling have experienced more losses than winning games. There are really no techniques in winning a game, it is only pure luck.
Quite agree with your statement with gambling that indeed returns to the players luck.
but some other gambling games are still based on theory, mental and mind. like a poker card. sportbook. it is very different from gambling by relying entirely on luck. for me gambling its pure for killing time and for fun. thats what makes gambling addicted for me.
