If the user is trying to access https://example.com, and an attacker redirects the TCP connection (or fakes a response to the DNS query so the user gets the wrong IP address) to a server that doesn't have the private key for example.com's HTTPS certificate, then the HTTPS connection will fail. The attacker is unable to serve their own content to the user as "https://example.com". HTTPS doesn't just encrypt the connection, but also authenticates the integrity of connections as being from the domain they claim to be from.

Spoofing a certificate isn't trivial but fraudulent certificates are a thing. This is why there are revocation lists and OCSP.
