This is due to the 3DS already having a huge install base, as that install base actively buys games. Even though 3DS didn't sell many units this year it has still sold the most software.
Also Sony hasn't published many new games on PS4 and PS Vita, while Nintendo have done so for Wii U and 3DS. PS4 and PS Vita games also cost more to develop than Wii U and 3DS games, so what really is a surprise is that the difference in profits is so small despite all these reasons.
