No, it only means that the device reported a match; or, that a match signal came in on a certain hardware port (since the scanner may have been replaced, tamperered with, etc.).

Not necessarily, it depends on the implementation. On Apple's case AFAIK the fingerprint mach doesn't simply report a match but also provides the system with the key(which was stored in a separate system) to decrypt the data. You can't simply connect a bogus fingerpront scanner to an Apple device and access the system, in fact that's the reason why unauthorised repairs end up having the touch ID or Face ID broken.

Same on Android. Fingerprint is used to enable access to cryptographic key.
