what if the hacker provided the public key for https connection? (www.youtube.com)

So this video explains how https works. What I don't get is what if a hacker in the middle pretended to be the server and provided me with the box and the public key. wouldn't he be able to decrypt the message with his private key? I'm not a tech expert, but just curious and trying to learn.

Not the browser companies. The parent CA would revoke Let's Encrypt's certs and publish that revocation in the certificate revocation list. When the browser (software, running on your system) downloads the new CRL, they will automatically stop trusting LE.
