You need to be exactly rank 20,000 to get that Decima card.

The Decima rewards at 2000, 3000, ..., 15,000 and 20,000 require you to be exactly at that rank. Consider these to be gifts for a few lucky players. To guarantee at least one Decima, you need to be at rank 1000 or above.

Unless the ranks are listed in a range (e.g. 15,001~20,000), assume that it means exactly that rank.
