This is really untrue in a lot of applications for instance in cryptography. But I do not know if random.ml is good enough for assymetric cryptography (where the secret key in the seed and the coding is simply xor with a random sequence of bit) This require not only passing all randomness test, but also making it hard to recover the key from a generated sequence of random bits.
