To become broke, that's the worse punishment of being irresponsible or unrealistic because its not about luck alone.
That's being stupid if you will only rely on luck because the more you gamble, the more you lose without consistency, and to achieve consistency, you need to develop your skills in gambling as that would make you confident, luck only does come unexpectedly so just erase it in your mind, if you are lucky then well and good but never consider it as your strategy if you are gambling consistently.
No one is permanently lucky or unlucky. Movies and books have implanted this idea in people's minds that there are those who are constantly lucky in gambling, in love, in everything, and there are others who are cursed or something, and whatever they do they encounter misfortune in the process. Such stories sell well,but they have little to do with reality.
For the most part, people who are called "professional gamblers" are neither more skillful, nor more lucky than other gamblers. They just have been more lucky than others for the last several years.
