You have a solid point here. In many things a minory messes things up for the majority.
Gambling is no different since we see the same amount of users not knowing what they are doing.

well its your money so you can spend it in a way you want even if its losing it on gambling games, i think its not wrong at all if you dont play with the amounts of money you need to live or buy food for yourself

I do not see the essence in gambling, when we play do not take the money, because basically gambling is about money hmm 

money, or anything of value, is essential to gambling, you cant "gamble without money" - that would be a fallacy, because just rolling a dice (or running a similiar chance-based event) without a wager and a prize is not gambling - its just, well, rolling a dice

Gambling is considered to be entertainment, but when people start to get addicted to gambling its very bad.

Yes it's people making gambling wrong, gambling being gambling is not wrong.
The key is to play for fun and not for profit.

well why dont you play then it from demo money or something like that if you dont care about money in gambling, in my opinion in gambling money is everything and nothing else is important i dont care about fun when i gamble

Gambling is no way beneficial to your financial life. It's practically a 100% chance of losing. (Long term, that is.)

Gambling could be in a way beneficial to your emotional life, as it is fun and gets your mind off things that are sad or bothering you.

Gambling could also be beneficial to your social life, as if you make a big win, people can respect you, and your wealth. Also, if you lose alot, people can think you're rich.

That's not true. You can make a profit of gambling. You need some solid strategies and know when to quit. Most people make the mistake of going all-in when they are on a losing streak. Also, playing games like poker require a lot of skill instead of luck. Good poker players can make good money!

It is not but being addicted to it an willing to risk averything just to have something to gamble with is. A lot of people does that.
