The point is that  stati stical  tests are not actually very useful for judging RNGs, not that there’s something wrong with AES. It’s easy to create an entirely predictable PRNG that will pass any given statisti calt est. In fact, this is basically one of the definitions we can use to define a keyed PRNG in cryptographic proofs.
