I know Haydn and Mozart were friends (and Haydn's famous remark about
Wolfgang, to Leopold, that his son was the greatest composer, etc.),
and I believe Beethoven took some lessons, briefly, early on, from
Haydn (?). But Mozart and Bach?
TIA
I doubt it very much because J.S. Bach died on 28 July 1750 and
Wolfgang Amadeus was born in Salzburg on 1 January 1756. Around 5 and
a half years after the death of J.S.

Perhaps the student read that Mozart "encountered" J. S. Bach -- meaning
that he became acquainted with his music. That happened some time after
he was born, and has often been considered to have been an important
influence on the younger composer.
Mozart did know Johann Christian Bach, J. S. Bach's youngest son, whom he
met in London when he (Mozart) was a child.

He calls himself "the Garden State's leading violist da gamba,"
... comparable to being ruler of an exceptionally small duchy.
