Definitely yes. Non targeted ads tanks click through rates which directly reduces price per ad impression. Not surprised if this is a xx% hit.

According to some articles I found from Google, already retargeted ads (someone went to an ecommerce shop, showed interested in a product, but didn't buy it, gets shown this product on another website), already has 10x difference in CTR compared to normal display ads which I think also take into consideration your likely demographic and interests. So even larger difference between completely random ads.
