With standard sizing of 3bb to 9bb, the actual number is closer to 33%, but that is not the point.
If one is trying to play unexploitably, you simply cannot allow your opponent to profitably 3-bet any two cards. If you are not defending 33% of your opening range to a 3-bet (will vary depending on sizing), you are doing just that.
This doesn't mean that the BB has to literally 3-bet any two cards to exploit you, but every time you open, you are giving him the opportunity to do so. It is just an inherent leak.
