Correct.
While no one has directly tested this scenario (using 2020 model year cards in a 2021 model year) Mazda does have two different part numbers.

I'd say give it another 1 to 2 months and the 2021 vehcile model year NAV cards will start showing up on the resellers on Amazon and eBay.
Per your chart...the 2021 MY TD2K66EZ1 should be 2020 year maps. I just got an ebay card but my version of maps is 2019. Probably got a reused or counterfeit card? The card is working good so far, no issues but a red flag being its loaded with 2019 maps. Thoughts?
