Polish Jews were targeted as Jews, but non-Jewish Poles were not targeted in the same way (i.e., the Germans were brutal occupiers, but Catholic Poles were not targeted for extermination).
However, there is a modern historical myth in Poland about extermination camps targeting non-Jewish Poles. For many years, there was a Wikipedia article about a fictional extermination camp for Poles. That theory is now discussed in a subsection of this article: https://en.wikipedia.org/wiki/Warsaw_concentration_camp#Disc....
The idea behind these theories is to draw an equivalence between what the Germans did to Catholics and Jews in occupied Poland, something that is popular among modern Polish nationalists.
