To hit an unintentional duplicate, you would have to be unlucky.
"... only after generating 1 billion UUIDs every second for the next
100 years, the probability of creating just one duplicate would be
about 50%. The probability of one duplicate would be about 50% if
every person on earth owns 600 million UUIDs" (source: (cough)
