The "7:" isn't part of the upstream (i.e. ffmpeg) version number, nor is
the "-0ubuntu..." suffix.
There is an explanation of the (quite complex) package version naming
conventions at [1], but unfortunately they don't explain the 7: prefix
(not very clearly, not to me anyway).
So as others have commented, you are indeed running ffmpeg 4.4.2, which
is also what ffmpeg's -version option confirms.
