Yes.
An NSA preferred "TRNG" device would be constructed from a stream cipher, its output would satisfy all randomness "tests", and the NSA would know all of its outputs. Thus, not random.
The Linux PRNG is similar to a stream cipher, its a cascade of hashes. Its output always "looks" random, but it is only actually random if its input is unknown, which is why the system PRNG needs seeding with true randomness to be secure.
