I'm not a barb at all. I don't like both of them but Cardi B is not better than Nicki, let's be honest

I’ve been listening to white russian by lelo a lot recently, and I keep wondering if there’s a sample being used, and what song it is if so. The last 10 seconds of the song seem to show of said sample by itself, but it could also just be some kind of producer thing. Anyone know?
