It's a very analytical, "cold" way to phrase it, yes, but you get this effect with many "human" problems that are studied scientifically, whether poverty, starvation, etc. Also note the same researchers can, and do, refer to the 'distribution of men' when discussing female mating preferences.

At a macro level, this is obviously true statistically. But do people experience it as such? You live in a non-polygamous society -- do you or the women you know feel like their spouses were forced on them? Because, to some degree, statistically, they were, as you correctly point out. But the mechanism is just via an accepted, background social norm... there are no arranged marriages, all marriages all voluntary, and everyone retains the option not to marry.
