Do you have a statistical source for that?
Here’s one
Mexico is 28.4 vs US Hispanic rate of 6.4 (and Mexico has draconian gun control)
Nigeria is 22.4 vs US black rate of 19.8.
Europe average rate is 3.0 vs US white rate of 1.7
At one point I took a look at California homicide stats, as California breaks out Hispanic from non-Hispanic (FBI combines Hispanic with white for criminals, but breaks out Hispanics for victims)

It was known in 1968 that more people were murdered in Mexico with knives than with guns in the US.
Look at the US Bureau of Justice Statistics.
