Comparing states reveals little; a list by population, and firearm restrictions, would be helpful however. Vehicular deaths must to be examined if one wants to identify "deadliest states".
The figures used in the OP also show little actual useful data.
For one thing, mass shootings are defined by the FBI as any shooting involving 4 or more victims. Almost half of those used in the stats of the OP are also domestic violence, with someone killing their families. This is much different that the crazed gunman opening fire on strangers, which is what the term "Mass shooting" invokes in most people.
If you take the annual average number of gun murders to be 11k, then the "mass shootings become such a small number.
There have been 934 people killed in mass shootings over the last 7 years. Of that number, 376 were someone killing 4 or more family members.
So the reality of the numbers is:
Average number of deaths from mass shootings per year = 133
Average number killed by family per year = 54
Average number killed by strangers in mass shooting per year = 80
So the number of murders by strangers in mass shootings is only 0.7% of the gun related murders annually.
And yet this is what the anti-gun crowd is focused on, almost exclusively.
