Why your mesh so high vertz. but mine is low vertz

I have followed the appropriate steps in the video (from beginning to 9.43). I use  Smooth brush too (hold Shift) like the video, I have enabled Dyntopo too. But in the end, my verts is a little.

How can it be like the second photo (the teacher's mesh) that I attached. Which is a lot of verts and much smoother.
btw, my blender version is 2.79. 

Thank You!

    Hey there, if you're using relative detail size, the amount of geometry depends on how close you are viewing the mesh. Zoom in closer for more topology. That said, there's no reason to need much detail at the stage you're at. Hope that helps!

    Hi Jonathan,

    'if you're using relative detail size, Zoom in closer for more topology' >> I see

    'there's no reason to need much detail' >> Yes, but I just want to know why that is so, lol

    Alright, Thank You for the response!
