Nah, perhaps this is just politics, maybe he was really a pro Trump and that's why he blurted this statement in public. Nothing to take serious though, maybe he meant different and didn't gamble that involved money. But since Joe Biden has won already, and just like any other state heads, he is oblige to accept the fact that he will be working on a new US sitting President and there could be chances in the policies.
I did not bet on this US Election, but if ever I was, for sure I'm going to lose because I'm going to bet on Trump winning the re-election.
