I don't think you really got what he was saying. I mean, 7k is a lot of money. Heck it's more than 4 years of minimum salary where I live, I would be super stunned if I bet my house on that and still lost.
I would even be stunned if I'm a casino owner and someone won a 0.00001% chance (and it has happened).
Are you saying no one needs to have emotion gambling? Then you've lost the point of gambling;)
I have never said that I have no feelings when gambling, it is not my intention. But to talk about the stunned when gambling, it is not a feeling that can happen to 7,000 dollars. I also agree that $ 7,000 is a lot of money, but why you must be stunned when others win, it is not your own victory

Moreover, gambling is not a means to get rich, I wonder why a poor person can bet their house for a game? I call it a fool
