Technically, the Nature article said that 1 in 3 "earth like" planets could harbour life. Unfortunately, the article didn't actually define "earth like". One could argue that Venus is earth like in that it is nearly the same size and orbits the same type of star (or in this case, the same star) at a "relatively" similar distance.
One could also argue that it is not at all earth like since it has no moon, a crushingly thick atmosphere, sufuric acid cloulds, and surface temperatures hot enough to melt lead.
