Any computer algorithm is just pseudorandomness, "ignorance" as you put 
it.  Dig deep enough into the algorithm and you can _predict_ the next
value, although doing so can be extremely difficult.

On the other hand, something based on truly random events, such as 
radioactive decay, is, well, truly random, if implemented properly.
