All of us here are theoretically prepared people to not become addicted to gambling and stubbornly resist any temptation to turn gambling into earnings. Because I, like you, believe that it will not work. All those who are in the black from gambling are either strong analysts who have achieved success in poker or good sports analysts who are excellent at placing bets. But such people are 1 percent, and even then it may be even less.
Being a responsible gambler depends on your character, and on that depends whether it is easy or difficult for you to be responsible or not.
As i always say, if you don't fall into this addiction there are other insidious and subtle ones, the important thing is not to let yourself be dominated and keep everything under emotional control
