Going by this link...Does this mean that there has only been 3,200,000 $2
bills printed up until August, and they are all star notes?

Yup.

I thought star notes were replacement notes?

Exactly so.

Do they normally print them first and use them as needed to replace old worn,
or destroyed bills?

50% correct. Star Notes are only used for replacing Notes 'spoiled' during the
printing process. Such as if a sheet were mis-fed into the press. Notes which
are returned as excessively worn and disposed of are replaced bu 'regular'
blocked Notes (not stars).
