It's the same old song and dance. The same statistic applies to people who carry a firearm.

The numbers are skewed heavily by the people who carry knives and illegal firearms for the purpose of engaging in criminal activities. Petty criminals, gang members, mobsters, etc. are obviously at greater risk of being wounded or killed than the rest of us, as are those unarmed citizens that they prey upon.

A far more useful statistic would be for people who have no criminal records (as well as those who have never been arrested or arrested & not convicted) who resorted to the use of firearms or knives to defend themselves against thieves, rapists & the like.
