I want to ask this here instead of reddit

I know you guys will be able to answer this for me if anywhere anyone can it's here..

So I am very knowledgeable of casino gaming. I understand what the house edge is of all games offered inside them. I even spent this past summer working for an Indian gaming reservation in California.
My question is comparing your typical table games blackjack baccarat exct, if I spend the whole day inside a casino every minute placing random bets table minimum bets I know that each and every bet I place my odds are close to 50/50 but more like 48-49/50 right so I know in my mind if I spend the day in this casino and I add my total balance up winnings and losses added and subtracted I know 100% certainty that my balance now will have dropped yes probably substantially. So it's a loss every single bet in my mind that small miniscule house edge will grind and grind away at my bank roll. Comparing this type of play to that sports betting online but in my example the bets I place are at Almost 100% certainty so I make bets at 1.01 -1.03 only to attempt with let's say 1 dollar minimum bets to try to win 1 penny.
In this scenario with each sports bet wager is there a house edge grinding me down like at a casino playing table games?
