Nope. You've got it backwards. The fact that you don't know what the vertical third of the court is proves that you have a life and don't spend all your time on basketball.

I believe you can visualize the vertical third of the court this way. Divide the court in thirds by extending the free throw lane lines from endline to opposite endline. The middle sections (containing both free throw lanes) is the "middle third" of the court.

You probably have to technically widen it slightly for most courts, since the lane is only 12' wide, but I think you get the idea.
