There is a way to earn low profits daily and that method is known as arbitrage betting through different sportsbooks though this does carry the risk of getting your account limited(Most cases) or closed(Rare).
I know people who invest big money and earn steady profits every week through this method. If their accounts get limited or closed, they move to other sites or create new accounts. You need a big bankroll to earn hefty profits though.
So many strategies that you can use if you have a lot of money to waste on gambling, its true that arbitrage are a good strategy but its not always profit. If you want to earn daily profit then go for a dice game and expect low profit everyday. Its not real if you earn big money daily or every time you play. Strategy wont work always even if you made analysis on that.
