As for 2, I'd say it's pretty similar to the bias (if it means what I think it means) I've said in my past comments, survivorship bias to be exact. People often only consider things that have happened when explaining, often forgetting about prior instances that ran contrary to what they've experienced at that moment. The view they see things get pretty narrow, not that I blame them, gambling can be pretty emotional at times.
As for 3, idk, I just spend everything I have in my bankroll. If we were talking about the entirety of our funds, where 10% here can be said to be the gambling asset part, then yea I guess it works as well.
