Sorry but this is nonsense. JBlack’s comment shows the argument works fine even if you take a lot of trouble to construct P(count|Y) to give a better answer.
But this isn’t even particularly important, because for your objection to stand, it must be impossible to find any situation where P(A|Y) would give you a silly answer, which is completely false.
