the encryption keys, why can't the government just sneak on them? (lemmy.dbzer0.com)

disclaimer: I'm just asking to get understanding of the theory behind network traffic encryption, I know this doesn't happen irl most likely.

Let's take https connection for example. I like watching revolutionary things on youtube and do not wish for authorities to know what I am watching, we accept here for the sake of showcase that google won't sell my watch history if asked (LMAO what am I even saying?).
So if I'm not mistaken since youtube has https implemented, our communication is encrypted, the keys are shared only between me and youtube. But when Youtube shares the key with me/my client the first time, is that also encrypted? Wouldn't the same question keep getting answered until there is something unencrypted? I know this is a bit too much unlikely, but if ISP automated the process of gathering keys and decrypting web traffic for a certain site with them for all users, would that work for them?
I'm taking https here as an example, while I have the same question for like VPN.

EDIT: Thank you everybody. I am not a member of this community, but every comment was a golden experience to read!

The other 2 commenters are wrong. URLs as they appear in your web browser are NOT encrypted when sent over https protocols.

The only data that is encrypted is POST data, and ONLY if it is sent over HTTPS.

So for example, a website login page crafts a URL like https://some.example.com/login?sessionID=12345678 and when you log in to the site extra parameters like Username and Password are sent via POST data, then anyone listening to your web traffic (like the NSA or your neighbor with wireshark) will br able to see the website and the sessionID, but not the login details as they will only show up encrypted.

However, if the site is ran by idiots who pass the data in the URL like this https://some.example.com/login?sessionID=12345678&username=Homer&password=Simpson, then ANYONE listeneing would have your credentials.
