EV

New to this site.
got a question about EV and pot odds on single table tourneys. im a bit confused about all the concepts.

Im in small blind on level 4 and am dealt TT. i have chips stack of 450 after posting. BB has 400 afer posting. Button raises to 200. I go allin. BB calls with AK.
In this situation, do we both have correct pot odds to play?
Are we both looking at +EV? Is it possible for only two players in hand to both have +EV? Was this the right move?
