What is Impressions Saying...?

Noob here. Say you buy an account with 15k followers. Say you post a cute image with lots of relevant hashtags. It gets 400+ likes/hearts and 10 comments out of 15k followers. On “Impressions” it says 1,170 accounts were reached and 1% weren’t following you. It says 1,200 impressions, 1,172 from home. From explore is 7. From profile is 4. From other is 20. Follows is 1.

What does all this mean? Is it poor or average? Would you conclude the account is botted as hell?

statistics, exactly
