If you had two separate sets of twins, say one set is male and the other female, and they coupled up and eventually had kids, would their kids be siblings or cousins on a DNA level?
This is just wildly hypothetical, but I saw a clickbait ad somewhere about a story, and now I’m curious if there’s any validity to it. It said the kids would all have matching DNA and were siblings

Genetically, yes. They would on average share the same amount of genes as they would with a full sibling.
But that’s sort of like saying that your identical twin is technically yourself because you have the same DNA.
