Not really. The guy with 25 guns can arm 24 friends. The state would hardly be arming people, the military would be directly involved on one side or the other. A civil war between left and right would absolutely not work out well for the left.

The stats are on number of owners, not guns owned

Statistically not really. I’ve been part of liberal gun groups in the past and it was hard to get any traction. Many of the members were also extremely fuddy and mocked people for having “evil black rifles” rather than their preferred .38 cal revolver and 130 year old bolt action rifle.

Republicans own guns at nearly 3x the rate of Democrats, according to Pew, and only a portion of democrats would be considered “liberal” and even fewer leftist, while nearly all republicans would be considered conservative globally. I would wager a lot of money that the proportion is even more skewed if you were looking at just ARs and other types of guns that would be decently suited for combat rather than grandpappy’s hunting rifle or a rusty old revolver.
