Sundin there is also a percentage of people who would lie their age even on nnid as silly as it may be.
But I believe the numbers are right considering it is still the first half of the gen, the console is a little expensive for gift and small total numbers. Most of the Sales were for Nintendo faithfull from 25-35 group.
On Wii the distribution would be quite different, and I think the 3DS have a bigger audience on newer folks while WiiU on the older guys mainly because Mario is older than Pokémon, the HW is cheaper and younger guys probably have more time as passengers or playing outside and Friends while older folks would play on commute (prejudice being an inhibitor) but at home preffer console.
