Extreme Tracking counter and Google Ads not appearing on Brave

Please advise why ExtremeTracking.com public counter as well as Google ads are not appearing on the following website: https://www.banknotes.com

It is located just under the image of the last book on that page and under the sentence: " Find More Numismatic Books Here "

First is the ad and under it is the poublic counter. Both do not appear on Brave. In fact none of Google ads appear on Brave. Please advise.

Because we block ads and trackers by default?
