No it doesn't. But here you go.
Lone gunman means ONE
Mass shooting means 4 or more as used by the fbi (1) and most major news outlets. Hell, I will even give you 3.
Majority armed location means a place where the majority are knowingly going to be armed like a police station, gun range, nra convention, etc...
If you need even more specific terms let me know but you can begin with those.
This is why debates cannot be had. People get side tracked into debating semantics instead of answering a very basic question.
your right travr6, three (two random souls plus the shooter) lost in a mall environment by a shooter using a rifle, shouldn't meet your criteria. i am glad you have defined the terms as there are quote:
There are mass murders and mass killings, active shooters and serial killers, mass shootings and mass public shootings.
The FBI, by contrast, doesn’t have an official definition of “mass shooting” on the books, but in 2014 defined a “mass killing” as one with three or more fatalities...(1)
...Mass Shooting Tracker...defines a mass shooting as one with “four or more people shot in one event.”
...the Congressional Research Service (CRS) defined a mass shooting as a homicide in which four or more people are killed with firearms—a definition based on the FBI’s definition of a “mass murder” as opposed to a “mass shooting.”
But other statistics, including a Harvard analysis, show that mass shootings—in which four people were killed....
(2) The difference between three dead and four dead might be statistically significant, but is morally negligible. Just hours after the Oregon shooting, a man shot dead his wife and two others, and injured a fourth person, in North Florida. On Friday, five people were shot outside a Baltimore shopping center.

and you say i miss the point of your question...
