You DON’T have to be extraverted to be a confident person. Society values extroverted people more! But even Extroverted people aren't always confident. Being confident is more than just being loud and a good talker. Confidence is built off of taking action in areas that you feel discomfort in. Confidence comes from knowledge & understanding after years of studying and experimenting because someone took the action to try and understand. Confidence comes from self-awareness. Knowing who you are and what you like.
