Yep, this is right. The problem is the round of 16 not being called "the eighth" or something like it's done with quarter-finals. It is "oitavos/octavos de final" in portuguese and spanish.
But that actually makes sense. Oitavos de final apparently google translates to an eighth of a final which means 1/8 which actually does refer to the round of 16.
The problem is people confusing the number of teams to the stage of the tournament. Technically, the final is 1/1 final, but has 2 teams.
