This means that you will never felt the excitement of gambling if the advice is not to gamble (will not lose anything). if you don't want to lose anything other than don't gamble, that is, don't invest, don't trade, then your money will be safe because you don't need to do anything. The definition of gambling according to my point of view is the goal to have fun, if you don't accept it because you lose with your own money, it means you are not ready to gamble, right before you decide to bet, you must be ready to lose/win, don't just hope to win.
