The answer is defently no.
the download rate is not the only factor that counts.
If the app is in daily use u dont need 1.000.000 downloads to live from that app. So the traffic counts thatswhy i try to make apps that are in daily use. Normally games are not, you can earn from games only if you got a big winner and many downloads. But this can change very fast until the game get bored and people look for something new.
But the good news are that with 1 mil downloads you can promote new games to those users and keep them with your products if you are fast enough. Instead of showing always ads you can show from time to time promotion of your new apps and get lots of downloads for free.
Good luck
Btw you promised to yourself in 2015 to make 10 apps, have not seen until now 1 in share your creation thread, or maybe you got big winners and dont want us steal your ideas
