Your torso should still grow more until 21, but yeah, considering you're "black" (i.e., most likely SS West African genetics), your proportions fall even more under the normal distribution of your ethnic group. It's nothing you should worry about.
I've mentioned it multiple times before, but most Sub-Saharan African peoples have longer arms and legs, while having shorter torsos, when compared to whites of the same exact height. This will mean a lower populational SHR and generally bigger wingspans, naturally. The source for all these claims are linked there.
Despite these anthropometric facts, I bet no one here knew about those until learning about them online, even if you saw black people everyday on the streets. This is why I say some people get obsessed with proportions in these forums, when they're not even uniform across nature, and they never batted an eye to the more differently proportionate people in the streets.
