It does not make any practical difference, if there is true randomness, or just something sufficiently complicated to be effectively random. In practice, it is appropriate to act like you have free will, because if you think you do not _and_ change your behaviour accordingly, then, of course, you rob yourself of the possibility to positively affect your life and that of others _on that level of abstraction_. It does not matter, if there is any determinism some layers further down (and, btw, there probably isn't), that actually _looks_ completely random. I know this sounds complicated, but the idea is actually pretty simple.
