How does my ISP (that has an offer on data only for a specific website) know that I am using the internet for that specific website and not others?

For the most part, it’s quite similar to post. They know you’re sending letters, and who you’re sending them to, and they know you’re receiving letters, and where they’re coming from, but they (assuming HTTPS) don’t know what’s inside the envelopes.
They need to know where the letters are going though, otherwise they wouldn’t get delivered to the right places
