XYES, it's very easy: you either offer good odds or not. If you offer good odds (a not too high bookie margin) then you have to accept that sometimes your odds are a bit higher than market average. If you spot this, limit the user stakes so he cannot make bets like this in future. Accept that 1% of your players will manage to win more than lose, this is not a disaster as you will still make a lot from those other 99%.
If you don't want to have a chance that at rare instances your odds can be above market the market, then simply take 0.1 off the odds your provider offers. If they offer 1,85, make it 1,75 etc. That way you will not have any chance that your odds ever get above market averages. Any respectable odds provider has a tool to increase the bookie margin for their clients, just ask and they will give it to you.

But if you are gonna offer 1,85 vs 1,85 odds margin then you have to accept the downsides of it too.

And btw on your website you advertise with "Bet on sports with great odds". How can your odds be great if they are never allowed to be above the competition?
