example: I have been playing gambling a few years, and lost so much. compared to victory. and if I count I never get the benefit.
Gambling is for long term but can't give you profits for a long term.
One can do gambling even the rest of his life but really can't take much profits out of here even for a long run.
This is true. gambling is fun and tempting to do it full time. But to earn money with your gambling for you whole life is not possible. Even for the most skilled players.
Thing is you can't be concentrated and skilled all the time.
You can use all kind if tactics and all kind of stuff but this will not help you to make profit on a long term.
Gambling is very predictable. If you make -ev bets, you will lose, if you make +ev bets you will win.
How can you say that it's impossible to earn money with gambling your whole life when there have been casinos around for so long?
How can you see it is predictable when it depends solely on luck. Do you know many succes stories?
No, reason why is there aren't. People tried and they failed miserably.
