Since your AdSense ban was for invalid clicks over 15 years ago, you might still be ineligible, but YouTube monetization is handled through the YouTube Partner Program (YPP), which is somewhat separate. You can try applying with a new Google account after meeting YPP requirements, though Google may still flag your history. Some users have been approved despite past bans, so it’s worth trying, but consider alternative monetization options like sponsorships or using platforms such as Scarlet App as a backup.
