Does Plastic Apple Card get 2% back?

I think either the person at the Apple Store misinformed you or you misunderstood or both.

Any transaction that involves the physical titanium card or entering a number will receive 1% Daily Cash back. Any transaction using Apple Pay or Tap-To-Pay will receive 2% Daily Cash back. Any purchase at Apple or a group of select merchants (Walgreens, Exxon, Mobil, Nike, Uber, Uber Eats, Duane Reed, Panera, some Ace Hardware, Apple) will earn 3% in Daily Cash back if Apple Pay or Tap-To-Pay is used. Any purchase from Apple earns 3% even using the card and online.

There is no such thing a plastic "Apple Card". The "Apple Card" MasterCard Credit is available in a virtual version in the Wallet app and a physical "titanium" version, not plastic.

Apple Card - Apple

Nothing has changed. You get 1%, 2%, or 3% cash back depending on the type of purchase you make. This goes for both the Wallet digital card and the physical Titanium Metal card. You are mistaken.
