No. End-to-end encryption means: only the sender and recipient can read the content, not any intermediate party or service provider.

And Google is not the sender of your password reset emails, they are a service provider, and they have full unencrypted access to the content.

Merely being sent over HTTPS does not guarantee full E2EE.

End-to-End Encryption means that nobody between you and the person you're communicating with can decrypt the data, not even the middle-man service facilitating the communication.

In the case of Gmail, the content itself is not encrypted. Google can read the e-mail. It's likely encrypted at rest, but Google has the key.
