I understand there are general concepts like Full and Split tunnel, I just can’t grasp the concept according to textbooks. What makes different models…well, different?

The internet works like the post system but faster.
Instead of sending a letter directly and having the post people see who you’re writing to you put your letter in another envelope and adress it to some VPN company.
They open the letter, find your letter already adressed to the actual receiver. They write their own adress on it to tell the receiver who they should answer.
So you basically put an instance between you and the receiver. The receiver won’t find out your adress, and the police can only find out who you’re talking to by going to the VPN with a warrant (and some are obviously out of their juristication, or simply keep no records at all)
And as a bonus: TOR network works exactly like this too, but instead of just using one middleman you put your letter in 10 envelopes that are locked and can only be opened by the correct next middleman. So noone at the start of the chain can find out who the receiver is, and at the end noone knows who the sender is.
