i think if you someone expert in gambling then anyone do not need to easiest way to earn profit if you are expert and skillful in gambling and i think these thing is very important in gambling.
I should say that is completely wrong what you understood about gambling because in gambling very important thing is luck to make some money and if you're not lucky for the day then all your skills will be wasted. If what you said is correct then by now many gambling houses should have been closed. Gambling is just for fun and don't think it is easy to make a profit just with gambling skills.
