it's all genetic.  If your Dad has chest hair, you probably will too.  If he's pretty bare, you are likely to be too.  I guess if your Mom has heavy facial hair (eww) you could tell if you are likely to grow some hair on your chest.  But there's a lot of variety out there.  I have more than I'd like, but you may still get some yet.
Is it normal for a 22 year old man to not have chest hair?
