Very anonymous, it routes all traffic though the tor network and blocks all direct connections except for the unsafe browser.
Of course tor cannot protect you from bad opsec, the user installing malware on it or a powerful enough opponent that can analyse both entry and exit nodes (or just owns 0 day exploits). But for most common people it’s pretty damn anonymous I would say.

has this ever been demonstrated in practice?
IIRC only for a tiny, non-selective subset of users unlucky enough to pick your two bad nodes. Otherwise Tor would basically be dead.
