I'm not claiming you'd be safe even with a gun. I'm not claiming there is any real government you are safe living under given a long timespan (maybe longer than even your own lifespan, but still these skills are passed down in families so breaking the chain during 'safe' times is still harmful).
To your specific question, probably not, but the better question is whether you have more of a chance with or without a gun? If you look at the Warsaw Ghetto Uprising for example, having a gun bought those people hours to days, which is better than nothing. Of course if you look at places like Chechnya, it bought them outright years that they were able to obtain independence from the brutality of Russia (even if not from their own brutality) as a result of militia activity in the first Chechen war.
