Yes, but "friend" has quite a wide meaning on Facebook.
Compare it to a WhatsApp group: there one defines exactly the people who should see a given message. "Friends" becomes mixed between "true" friends, neighbors, colleagues, ... people you once we're closer with but passed ways to some degree, ... after a while it's semi-public at least unless you have a strict (un-)friending policy. For average users the visibility is also hard to understand.
