Do you mean that a given user has a quota limit of 100TB on a filesystem
with a capacity of 300TB?

Yes.  That's how filesystems work.  If my supposition above is correct,
even though a given user might only have a 100TB quota, df still reports
to them the totals for the filesystem, not their prescribed quotas.

It is being shown correctly.

You can use the "lfs quota" command to get the particulars on a user's
quota and usage of it, etc.
