Admob estimated and final payment

Hello guys,
sorry because this is not technical question about Kodular it’s self, but I have issue with Admob, my first app got alive in Google PlayStore was before a month ago and I got nearly 2 thousands impressions and it gives me estimated earning equals almost 7$, but when I go to payment it shows Zero
Can anyone explain to me why or how to solve it ??

i think it will be added in your earnings after a month
