Well maybe it's because Yan Dev actually stated their ages. The classes are divided by ages and Yan shit said that he 1-1 classes were for 16 year olds, the 2-2/2-1 were for 17 year olds and the 3-1/3-2 classes for 18 year olds. Also please do check the canon wiki if you're still confused. The rivals who have unknown ages have around 18 or around 17 depending on the rival not unknown.
