Uniform regulation across an entire country makes a hell of a difference.

The EU has a uniform gun regulation zone, the UK has even enforcement, Australia didn't "ban guns" it simply made a few low population territories and states adopt the same regulations as other high population states had; 12 year olds can join gun clubs, every sale requires a registered seller and and a background check for the buyer, contractors can get semi automatics for feral pig culling, my neighbour here has an arsenal of weapons for shooting at all distances out to 5,000+ yards (yes, ULR five thousand yard shooting is a thing here).

The USofA isn't at all united wrt gun regulation.

Twue patriots seem to love moving weapons across state lines and arming conflict areas for profit, no real readily accessed central database, tip toeing around removing weapons from domestic violence offenders who can readily replace what, if anything, is taken.

Australia once held the world record for victims of a single mass shooter - we've had nothing remotely like that since uniform regulation and enforcement.
