Respectfully disagree. He'll pay out to avoid inconvenience; but his psychological makeup is to never, ever lose.
There's a 2-hour or so documentary (or actually two such) by Frontline exploring Trump's life and that of his political opponent for President in minute detail. Frontline airs these shortly before each US Presidential election. The latest one, about the 2020 election:
An election-year examination of the moments that shaped Donald Trump and Joe Biden.

It's 2 hours and is likely far too long for most people - but it's compelling viewing and well worth your time. The previous Frontline about Hillary and Trump was equally fascinating.
Anyhow - Trump is quintessentially, existentially unable to admit defeat. And this makes him a fighter.
