How about this one? Who thought that winning is gambling is not possible, damn, small capital to $40 million, must be a gifted gambler, I wonder if there are many of them in the planet.
Though it's possible, but we should not think that this would happen to us, winning in gambling is not just for everyone.
In fact, winning is only for few people while casinos always makes money at the end of the day.
I am sure not many people can win much money in gambling, especially for that such amount. If he can win that much money, he is a very lucky and gifted gambler because to win small or medium money will need luck and effort, and sometimes we can lose some money before we can win.
Yes, that is possible to win that amount of money, but the probabilities will not too big. The rest will get their loss without a chance to recover their loss or even win a lot of money. But perhaps, a gambler can win for a total of that amount in a year, but to get a big winning will need big luck.
