That's just a string, it doesn't mean that you actually have all the latest patches:

> Most non-Google-certified operating systems are setting an inaccurate Android security patch level by ignoring the non-AOSP portion of the patches. GrapheneOS doesn't do that but most of the other AOSP-based projects not being certified by Google are doing it. OEMs were caught doing it too but it's not clear if it was intentional in most cases as it is with the alternate operating systems.
