ELI5: What is the difference between Cable TV and Cable Internet? Why doesn't TV ever need to stop and load like streaming services?

As far as I know everything is coming through the same wire. The cable box starts almost instantly when you pick a channel and is consistent from there.

When using streaming services there is a load time, and after that there is always a chance for it to slow down, lose quality or pause itself.

Both are HD feeds, and both are coming through the same wire. Why can't netflix achieve that same consistency?

Cable TV is 1000 guys in a room all screaming at the top of their lungs about different subjects. You and anyone else interested chooses which one you want to listen to and go stand next to him. 

Cable Internet is a million guys in a room being quiet, you ask a few questions until you figure out which one you want to have a full fledged conversation with, then you go find a quiet out-of-the-way corner to have that conversation in. However, there's only so many corners, and other people may interrupt the conversation, or they might want to talk to the same guy and his attention is divided between the two conversations.
