Am a casino pleb myself, but I disagree with your advice about playing games only with the lowest house edge. Why? Because house edge isn't everything. Some of my biggest wins were from games with high house edge.
Games which I usually play are slots, Baccarat, sports betting etc where the house edge varies between them to a large degree. Fun > House edge in my opinion.
I am with you on this, house edge should not be total, I was so amazed when I was reading what the OP wrote as if it was a fixed budget affair. Dice rolling and casinos, in general, do not work like that as nothing works 100% with gambling, but to just follow someone's mind/instincts and variable approaches, is not fixed advice from anyone.
No one should be total in a certain approach to gambling and must find a way to play based on what their minds are telling them at that current time.
