Adobe Acrobat (32-bit) vs Adobe Acrobat/Reader

What’s the difference between the “Adobe Acrobat (32-bit)” (software ID 239) and “Adobe Acrobat/Reader” (software ID 303) applications? I first thought it was about Pro vs Reader but my understanding is that if a user signs into their licenced Adobe account after deploying 303, they “unlock” all the Pro features, is that correct?
