There's no success in gambling. You just got lucky in a a very short time and then lose afterwards. I have lost alot many times in gambling and until now I still gamble a few times but i dont bet big amount, it's just like gambling for fun, I dont want to be broke just by losing all my money in gambling.
Being lucky itself means to people being successful. Because not every one can be lucky and if you are lucky then mostly success will be near or with you and you can easily achieve money, fame, name etc. In gambling as well you require the luck with you to be successful in making the bet win.
It is true that you need to be luck to be able to be successful in gambling, but also you need to be smart and have self control so you won't lose, if you make a bet and you lose once and twice in a row you don't need to keep going, there is no need to multiply your bet in order to compensate for you loses, just call it a day and leave, because successful people are not just winners they are also the ones that pick their fights and know when to quit.
I have even met some people who are crazily lucky in gambling and other things where chances of luck are needed such as raffles and lottery. Since gambling is just random and theres no way or strategy for you to win, its really just based on luck. Most of the time, these are the ones who find success in gambling. Im not as lucky as they are so I dont usually find success in gambling.
