The exact answer, as I understand it, is a bit more nuanced. In
particular, you referenced the PRNG. I believe libsecp256k1, as
currently written, relies on an implementation of RFC 6979 instead of
using a PRNG. I'm guessing this is done for portability reasons (no
need to hook into the OS's RNG).
Otherwise, yes, I believe this answer is basically correct. There are
still some crypto functions not covered by libsecp256k1, at least at
the API level. But, for consensus-critical functionality, I think 0.12
will be rid of OpenSSL.
