Regulating gun ownership isn't the same as banning guns, and correlation is not the same as causation. I could say "Norway has very strict laws when it comes to owning guns, yet our murder and crime rates are way lower than in the US." and that would in the same way not prove that strict gun laws means less crime.
Most of the proposed regulations that are intended to do anything signficant are defacto bans on certain types of weapons. So yes, they are gun bans in all but the literal sense.
And the bolded was my point, certain places in the United States have obtained low crime rates without gun control, there is nothing preventing other areas from achieving the same by targetting causes of the crime rather than means by which the crime manifests.
