..... and we know that in the case of sports betting the house edge can vary wildly and you do not want to make a bet in anything that has a house edge otherwise your chances of beating the casino become minimal.
I don't see any house edge on casino, but that's just for me.
You are not being against a casino when you put your bet on sports, you are betting against the bettors, casinos just take a portion of your winning which is the juice, normally 5% to 10%, depending on the sportsbook, but for me, normally I do bet on odds high that +100 so I don't have to pay for the juice.
