Well, the definition of randomness is basically the inverse of determinable... it is something that is not predictable. The important characteristic for randomness is that there exists no knowledge that, if possessed, would allow you to predict the outcome. In that sense, free will meets the definition of random. In other words, not all randomness is free will, but all free will is random. So yes, anti-determinism does not prove free will, but determinism would disprove it.
