Yes, and those are *true* random numbers, since their source is physical rather than algorithmic, that is, the numbers are generated from random noise (thermal and electrical) read from physical devices.


For testing, though, it's always good to rely on a (good quality) *pseudo*-random generator, so that you can reliably generate the same sequences all the time.
