Not really. A fixed seed means you will always get the exact same serie
of numbers. The seed is the initial condition of your random generator,
and a random generator is a totally predictable, deterministic process.
The (pseudo) randomness is a consequence of having a random, unknown
seed, causing the serie to behave seemingly random to most statistical
tests. This can be time, keystrokes, etc...
