I've always assumed people are largely the same, socially. I.e. we enjoy being with people we mesh with, and don't enjoy being with people we don't mesh with. The thing is, you can like people you don't mesh with. You might not have a single bad thing to say of a person, yet still have no interest in hanging out with them. And then, surprise, being forced to do things you don't enjoy is draining. Especially when it involves long periods of politely choosing your words and facial expressions to pretend you're not bored/frustrated. The only thing that makes an "introvert" is when the genre of person they mesh with happens to be more numerically rare. There is a ton of variety in humans. It doesn't mean anything significant that your "group" is small.
