DFP revenue are very high. is it real revenue or is it an estimated


hi recently i join DFP and i set the cpm randomly high around $20 so the revenue also goes high. is the revenue i see on the report real or just an estimated. with 70,000 impressions i made $1500 and who is going to pay me for this revenue if it is real. i know that adsense will pay me for those adsense win, but how about the other advertisers how do i know them and how do they pay me. thanks for your support.https://gyazo.com/0eb75290150d656e21f18879ad5995ce
