need help with mobile games on flippa

I would like to buy a few mobile games on this site. but admob campaign strategies confuse me. There are games that provide beautiful earnings with very low advertising costs. how do they do it? can I trust games here? for example

This game is 2 months old. install number 1000+earnings report:

costs : $ 60 Revenue : $ 843


is this true ? can I keep it if I buy it? Thank you…
