It has more than the amount necessary. However, not all of the ATF will come out on a drain in fill... hence
IraHayes 's post below about a specific procedure.

It’s also generally advised after you perform the procedure, to drain and fill again after a couple hundred miles, as a lot of the old fluid will have remained in the TC. This way you can ensure that most of the old fluid is gone from the system.

It's a dilution problem. You'll probably never get all of it out. In fact, you would be lucky to get 60% of the original fluid out on each drain and fill. I would just decrease the intervals of each ATF drain and fill instead of doing another one a couple hundred miles after the previous. Perhaps every 40-50k.
