What happens when online betting shop makes a mistake?

Factual Questions

In Colorado so not illegal
I have a parlay going and one of my teams lost on a last second play (I take the money line on parlays not the spread) for my only loss. It is still showing as an open parlay 24 hours later since the last leg is tonight’s game. What happens if the book pays off my parlay when they shouldn’t? Is it my money and oopsie doopsie? Do they have a limited time to take the money back? Can I pull the money out and hold on to it and just give it back when they realize they made their mistake? If I do is it uncollectable on their part since it’s a gambling debt?

I know this sounds specific to me but I think the answer is still a good GQ.

FTR I don’t think they will payoff because it is not showing any cash out amount. More an error of not closing out the open bet.
Assuming the ToS says every dispute will be ruled in their favor as far as they are allowed, I’m assuming a time limit still applies even if not in the ToS. They can’t come back and say, “Hey remember that bet four years ago?” can they?
