Isn't it supposed to be "anything" instead of "nothing?" What's it mean?

You're right! Here, "nothing" does mean "anything." This way of speaking and form of grammar is part of "African-American Vernacular English." This is the English spoken by Black urban communities, mostly in the USA and Canada. So if we looked at what is considered "correct" grammar, this would be considered incorrect. However, it's used so much within certain communities and spaces that it's not considered wrong within these contexts. Ex: I'm not scared of nothing. = I'm not scared of anything. Ex: We didn't do nothing last night. = We didn't do anything last night.
