No, gambling is not an entertainment, the way people think it is to gambler. Gambling is a business which many gambler like to earn something good from their gambling in the gambling center. Is not an entertainment where people joke with other people to make them laugh in the occasion just to make them happy in the invent.
Gambling is a serious business we run with experience for you to earn something good from the one you have gamble in the gambling center.
What are you talking about?, gambling is not an entertainment because people don't make jokes while gambling?, something can be considered as an entertainment without being funny...
Regardless of what is your definition of entertainment, as a gambler as long as you can not make a stable amount of money which you can count on, it would be considered as entertainment and not a job, a business or even a side job/income, gambling is only a business for the casino owners because they did their calculations on the expenses and incomes and they make their money whether you lose or win.
Well, what we should be reminded of is, there are two sides to a gambling business, the gambler and the bookmakers. To the bookmarkers, you might consider gambling to be a very serious investment or business while to the gambler, it's big time a game of luck and no one would really take a game of luck too seriously. This is what makes it an entertainment. You don't put all hopes that it must favour you or play out the way you've visualized it! No, that's not how it works.
Yes we all hope to earn something if possible but then, the loses are more frequent than the profits. Which gambler would take that for a serious business? I am sure I'm not that gambler, are you?
Don't put all hopes in the bets, which ever way it turns out, just smile!
