It sure looks like it as that number is only about 50M below the 32-bit signed integer limit of 2147483647. I think your lucky hat ended up being a bit too lucky and the universe decided you needed to give something back, even if only to the tune of a mere 100M Qi coins.

Double and give it to the next person gone wrong...

Yep, I'd recommend exiting and not saving the day if you ever want to use the casino again on that save as outside of file editing and paying exorbitant fees that aren't worth it, there is no way to get yourself out of that debt.
(you can't use the slots or table without casino coins, so can't use bet your way out of it)
