You know it is a win-win situation for you because if Trump somehow comes out as winner then you win all the bets you made on elections as the Biden bets are already paid as winner.
The chances for a Trump win is highly unlikely even if they recount all the votes, but the scenario you said is real as they already settled the Biden bets and if there is any change while counting again then the house will take the damage and it will be a huge burden.
I might avoid betting on elections completely but if even I make any bets they are always going to happen at stake from now. The way US media handled this election and the results it really concerns me because it should be the people who vote and elect the president not the media channels.
Usually i used to avoid political bets but the way in which the media is lying about things you never know what will happen and in the last election no one gave a chance for Trump and the odds of him winning was high and even this time the odds were pretty decent for his win and there is nothing wrong in waging a small bet on him.
