I can really understand this and I also do not have any problems with this due to the fact that its not bad at all in my eyes.
Gambling should also not take over your life or something near that due to the fact it has to be for the fun.
yes i also disagree with this statement, i think we are playing gambling not for making life, we just enjoy gambling and always try to make some money, and those people who only try to make a lot of money from gambling then it is not possible you cannot make money in gambling on permanent bases.
Professional poker players can make money out of gambling but its not a stable income after all even if you are the best player in the world, luck still plays a part in the game, you can play perfectly a hand but when the river comes your opponent gets the out that he needed and now you are beaten.
