That is why I only deposit the amount I feel I am comfortable losing, of course I want to win but I know it might all go to the house so that is how I control myself. I just gamble as much as I can afford losing without depositing too much.
That means you are not a real gambler, the level at which you gamble is not as high as those that loose huge sum in the gambling industry, a real gambler deposits big sum so they could win big sum in return. It takes time to control oneself out of gambling problems, gambling is not for everybody, if you find out that it doesn't favour you, quit away from it.
Based on what you've described then a sponsored streamers could be considered a real gambler? They also did deposit with a big sum of money although it was not from their own pocket?

I tend to agree with the thoughts of two individuals above me, IMO a real gambler doesn't depend on how much sum of money that you spend in a session but rather understood exactly what they are doing and how much they spend on each session.
