In some regions, only YouTube Premium subscribers have access to this download feature. If you're short on storage, you might need to free up space on your iPhone, Android, Mac, or PC. This is because offline YouTube videos are kept in encrypted form on your device's internal storage, even though they aren't saved as local media files. Downloaded YouTube videos are only stored in the YouTube app and not on your device's storage, but you still need to have enough space on your device to be able to download YouTube videos.
