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.

Many years ago I manually removed all CAs from my trust store and only added those I needed. Turned out that from roughly 160 trusted root CAs I needed about 10 to 12. I stopped because it often was very difficult to figure out which CA signed the cert for an app that was failing. The final nail in the coffin was when I was late for a business meeting and the only way to get a parking space close enough to my destination was by paying with an app I'd never used before and finding the right root CA under pressure was too much. I really wish we had more and easier control over who we trust.
