I don't really think is that possible to win with single game per day, because gambling is not wordy to be trust no matter how much effort you put in bringing single game per day it most not surly be successful everytime.
Yes, there will be times where you will lose because you predicted wrongly but it wouldn’t be that common in my opinion. Single bets are a lot simpler and focusing on only one event allows you to truly focus and analyze all factors that could possibly affect the match.
Because just like as you mentioned gambling still remains the same no matter how you predict, what would happen will still going to happen, no trees when comes to gambling.
I don’t know if that is a saying about trees and gambling but yeah the best we can do is analyze past performances, evaluate current chances, and bet.
