That’s where we are seeing things differently. I would say even catsup is basically a sauce. And the rest, but for the relish, the same. But if you are only looking at more elaborate condiments for the title, then we are not talking about the same thing.
As for me, I like pickles, but really see no difference between saying that and someone saying I like bbq sauce. It all hides/enhances the meat in some way that really isn’t unique to certain toppings.
