Gambling is an uncertain win-lose betting field.There is no guarantee that anyone will win a single bet. So it doesn't cross my mind whether this non-guaranteed gambling should ever be preferred as a major source of income. If there was a possibility of monthly or weekly profit from gambling then it could only be taken up as a profession or a job. But there is no guarantee that you can win from this gambler's bet every day. If you win one bet there is a chance of losing the next so this uncertain income should never be taken as a part time or full time job.
No guarantee at all, if there's someone who can manage it's a small percentage for sure, we won't see a lot of gambling businesses if gambler can take advantage of the services, instead, gambling owners are the one who really taking advantage of people who are involved with gambling, they are being allure of things that they misconceptions regarding to gambling.
It's a tough competition between your knowledge and emotional control, with that capabilities chances to earn is not by far but if you can't deal with it, better to treat gambling as a source of entertainment instead.
That's a fact but strangely not all gamblers can accept the statement of fact that really happens very often especially to those who are always excessive in their involvement. This is a business that generates fantastic income for the bookie, lately I often see some small gambling situations caught by the authorities, after being traced and interrogated it turns out that they can generate millions of dollars in turnover in just a month, isn't that huge? of course, and than the bookie can get that money? obviously from the many stupid gamblers who always bring the wrong mindset as it comes to earning.
Indirectly gambling is a brainwashing activity for those who are very careless, casinos are very smart in terms of attracting more audiences, 10x losses in exchange for only one win, isn't that unbalanced? obviously, but gamblers don't realize about it, the point is for them when they get a win it means everything is fine, if they look at the records I think they will be quite surprised when they find out that the amount of winnings is much greater than what they got at that time. It's all just because of wrong thinking and excessive expectations, they can't consider that gambling is a place of fun, it's because their focus is more on the "odds", when there are no guarantees.
