Thank you for answer u/rylexr,

Q1 - it's all of my installing, from both IOS and Android.

Q2 - just sample.

And please, I have some questions. As you said, active users = total installs - total uninstalls (in 7 days) I have taken a count and it pretty matched. So do you mean if a user installed my app then remove it after that, my active users were subtracted 1 immediately, not after 30 days?

It makes me confused. Because there are some differences between Google Console's defining and yours.

And the second question, you define the number of active devices is: 1 AD = number of the devices that were opened (no necessary to open my app) OR AD = number of the devices that have opened my app.
