Drumeo is the answer for a 16-year-old, or 60-year-old. There’s enough content there to dial in exactly what he wants to learn, see where he wants to be with the more complex stuff, and learn from a bunch of actual pros. Can’t recommend it enough! I’m a lifetime member.Also take a look at Drumeo. They've got plenty of content including beginner level (I'm assuming the 16yo is a beginner).
