My mom told me America (the US) was the first country to abolish slavery. Then I found out that isn't true. Was she brainwashed?

We were sitting in the car talking about racism and slavery and slurs and Democrats and Republicans, and she brought up some interesting point about the US being the first country to abolish slavery. I was so excited to hear the facts, as she was telling me about Africa not having enough resources so the US shipped the slaves over and white slave owners bought slaves from a Black man, and the US became the first country to abolish slavery.

But, it wasn't America. I just found out it was Haiti. Is her history vision Euro-centric? By the way, she told me Kamala Harris is not even Black, she's Indian because of her name and her husband.
