It depends on the number of bits you use to generate the resource. There
is a certain probability for calculation errors on a computer. Because
of this error probability also in your scheme duplicate IDs may be
generated. If the number of random bits is enough to get down to about
the same probability for duplicate resources, there is no difference.
Or in other words: yes, random algorithms (of type "Monte Carlo
algorithm") may result in wrong results - but deterministic algorithms
are not es deterministic as you might expect, if they are executed on
So I'd say which way you are using to generate the resources depends on
your goals. E.g. you might not want to show IP addresses or PIDs to not
leak information about how you set-up your server.
