Gambling can be considered as wrong but it also depends on your religion and how you are doing it what people already said.
If you enjoy it its not wrong but if you are doing it for the money its very very wrong!

Gambling is only wrong when you are losing a lot of money with it and that happens only if you are addicted to it and that is bad if that the case is.
Because it is all wasted, but it is not that wrong if you are playing it for fun and invest with only small amounts.

Gambling is not wrong for some players when they can make very good amount, but if we are on losing streak and don't have luck than it is really wrong and will put into more worse situation in future, mostly it depend on the condition how we are going with gambling.

People usually look down on gamblers unless that certain gambler takes home thousands of cash. They think all gamblers are associated with drugs, alcohol, etc. I believe the reason why people frowns upon gamblers is because eventually, gambling leads you to a path that you never want to go. You sell the furniture inside your house piece by piece for the sake of gambling. You'll end up screwing your life.

It's really depend on the person though. I mean, if he gamble with all his money and make his life broke, yes it could be wrong. But if the person can handle himself on gambling, no it's not wrong.

all depends on your goal to play gambling. if you want to earn income from gambling could be wrong.
because when you are defeated, you will get frustrated and blame, as if gambling is wrong.

It is beneficial in a way of earning fun, like feeling thrilled, excited challenged, or in some way of feeling those emotions like that, that is cause by knowing your money is at stake and might actually lose.

And It is also a losses because actually in gambling, there is no such thing as earning more than the amount you put at stake from the first you started t play it. gambling is for entertainment thus betting n it will actually make your coin lose, as gambling are full of risk that you cannot even barely win an amount and cash-out it due also to thinking that betting it again might double it that in contrary it didn't but in worse thing it all lose.

It is hard to stay away from gambling when you are addicted to it because you are not realizing how much money you lost and that you are thinking that winning is kind of rare in gambling so that is bad of gambling itself.
And if you can realize that than it will be the best way to stay away from gambling.

In Islamic it is forbidden its mean that It is wrong. but for other religion and states I have no idea.

In my view gambling is not at all a problem or wrong till you don't have greediness of earning more through gambling. When you become more greedier the possibility of losing increases.
