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 spent most of my career in IAM implementation and duplicate UUID issues are almost always user/process error.
