You seem to be confused. Need-based aid is not the only kind of financial aid. Merit-based scholarships (academic, athletic, artistic, performance) are also financial aid, as are federal direct loans.
Based on your reported income and assets it’s highly unlikely that any need-based aid will be made available from UT Austin, and if you haven’t yet heard about merit aid it’s possible that none will be forthcoming and the student’s net price will equal the published COA.
