That list is about murders. Not about gun related crimes/injuries.
Ok, here is the gun related homicides per 100k. The US is 8th.

Not great, but not as bad as it's made out to be, especially when the difference between 8th and 20th dwarfs the difference between the top 3.
That being said in the vast majority of crime is the US is localized in very small specific areas, so I'm not sure what guns or gun control matters in one instance or another. There are rural areas where everyone owns a gun and crime is unheard of, then there are areas in Detroit that are like war zones. Gun control won't apply to these areas since they aren't exactly gung ho about obtaining guns legally, and like everything else in life, if there is a demand and the product in demand isn't something extremely limited like enriched uranium, then the supply will follow.
