Because I can guarantee you that whatever scenario you concoct to take on a person with a gun while unarmed yourself will be unlikely, far fetched, improbably and far, far likelier to end with your death than subduing the gunman. It’s not impossible, no, neither is surviving when the plane you’re flying in blows up in midair, but it’s unlikely, and I’ll guarantee you that whatever the scenario you do come up with, your odds of surviving will greatly increase if you do possess a weapon.

By the power of Google I shall bring forth data.
It is hard to say how poor your chances are as I know of no relevant source, so lets do a search and see with what we come up with. In order to find people who try to disarm shooters I am looking up: “school shooting” hero. That should give us what we are looking for, I will illustrate all the ones I find that are at all relevant (for example, not involving law enforcement taking the shooter down).
1) Fifteen year old brings gun to school, starts shooting when confronted, taken down by unarmed faculty. One dead and two wounded. No word on if the injuries happened before or after they went after him, so it is hard to say how it went for them. They definitely won out though.
2) Kid brings in gun for some vengeance and the principal takes him down but pays with his life. Other unarmed teachers finish restraining him. Only the principal is hurt.
3) Columbine. Teacher tried to stop it, was killed, and accomplished nothing.
4) There are a couple here, but only one I found where and unarmed person attempts to stop the violence. A teacher struggles with and chases off a student who had the gun out and was threatening others. One shot fired, no injuries.
5) A student shoots two others and an unarmed teacher disarms him. Teacher uninjured.
6) Kid shoots six others with a rifle, then pulls out a handgun. Assistant Principal talks him down without even having to physically restrain him.
So, we have six instances on the first two pages of the search. In four the unarmed person is able to stop the tragedy and make it through. In one they stop it and die in the process, and in the last they die without stopping it. Though this is entirely unscientific I think it begins to show that it is not as completely far fetched as you believe. People just don’t expect you to try and stop them, they expect you to run away and get shot in the back while fleeing. I agree it is probably pretty dumb to charge in at a shooter when you are unarmed, but it can and does end these situations with much less loss of life.
Though your odds of winning probably go up with a gun, so do your odds of hitting someone else, or other people mistaking you for the shooter.
