That doesn't mean it's running BSD. For example, MacOS runs a non-BSD kernel with lots of BSD networking code added on-top. It is not a BSD-based Operating System but it does use BSD code to create it's environment. I would not for a single second believe that the PS4 runs an unmodified FreeBSD kernel. There is just no upstream code to support this claim.
Not sure about PS5.
