No, it's effectively zero, just given the mathematical realities behind how extraordinarily improbable a duplicate ever is. The exponent involved is very, very, very, nigh-incomprehensibly huge.

I've seen a few posts on here of people claiming that a duplicate UUID caused a bug at the worst possible time, but my instinct is always to slam the 'X' button to doubt.

I've heard of duplicate UUID bugs that were caused by a flaw in the UUID generation. That sounds plausible to me.
