I read that https encrypts your information. So for example your isp won’t know exactly what you’re looking at, just the website you’re connecting to. My question is how far does that encryption go. If I google “what does https do?” how does google know I looked that up if my connection is supposed to be encrypted?
Another example would be youtube. From what I understand my isp would know I’m on youtube and likely watching a video due to my bandwith, but they wouldn’t know which video I’m watching. However youtube would know. Why is that?

Your browser encrypts the traffic with the key of Googles server. So Google is the only one who can decrypt the traffic. And when you visit Reddit your browser encrypts it with Reddits encryption key and only Reddit can decrypt the data.
Your browser gets the key from the server when it connects. And it knows it is the key of the server because it comes with a certificate that is digitally signed from a certificate provider that is hard coded in your browser or your operating system as a trusted provider.
