No its not! Pretendo is still growing.

if we compare day 1 number of user vs now u can see the difference

NES died too, no love for *it*? /sarcasm

Comparing day one to now isn't really fair as day one is generally more likely to have more users than years after. There was popularity in both systems wiiu and 3ds with the official servers being shut so the revival of such will share that, which obviously diminishes by time.
