Yes most martial artist well tell it is very dangerous to attack some one that is armed no matter how well trained you are.

Well, I was speaking to unarmed confrontations specifically.

Against an armed assailant, the choice may not be yours. If he gives you an opportunity, it is probably best to take it and possibly die trying. You are a lot more likely to survive a shooting than an execution.

I have heard two strategies that should be used against armed assailants. The first was to comply with their demands. While this seems like a bad idea, statistically, it has the higher chance of survival for the victim. The second thing, and this was only to be used if the victim knows what he or she is doing, was to create a distraction, secure the weapon, and blind the assaulter with something like mace. If you have a gun, you can just secure their weapon, and point it at your assaulter (or hit them across the eyes - that could blind them permanently though). Either case, if you have multiple assaulters, and at least two of them have guns, you are probably screwed, gun or not (if they find a gun on you, it'll probably make things worse).
