Re: "I need to update my payment info for my AppleTV account".

Your Apple ID is the one account you use to access Apple services like the App Store, Apple Music, iCloud, iMessage, FaceTime, and more. It includes the email address and password you use to sign in as well as the contact, payment, and security details you use across Apple services.
