Authenticated encryption is an all-in-one encryption form (algorithm) that provides privacy, integrity, and authenticity together.

End-to-end encryption is a concept where only end-users read the encrypted message. end-to-end encryption aims to prevent man-in-the-middle eavesdrop such as telecom and internet providers. The transit data in the servers are encrypted and the service owners do not have keys and the possibility to decrypt it.

they are totally different.
