As i think gambling is not fun anymore when someone is on losing streak than how he enjoy and entertain himself to stay online on gambling site, it is fun when we are making good good profit there so it makes our life easier and can generate free money for us.

Let me ask you what is your definition of FUN? Fun can be difened as happy, it also can be defined as entertaining. So what do you think people refer to when they say that gambling is fun? It's the entertaining one right? Gambling is entertaining because it's a game. You said it yourself.

It all depends of your approach.
If you have to win some cash, to for example, pay your debts or simply buy food than
its not fun its a struggle, a matter of life and death. Stress and anger will eat you alive. Definitely no fun in that.
Have some bits to loose? Nice evening with beer and chips along few cards and you have some entertainment.
You loose, you win doesn't matter, all what is important is hedonistic pleasure and maybe a little thrills, not especially cheep thrills. Gambling when rich -> pleasure. When poor -> nightmare.      
  

Gambling is fun when you are winning, but when you are on a loosing streak I don't see any fun in that but more on giving me more stress and problem.
