I believe you misinterpreted that to mean that the zombies have lower defense, and are therefore receiving more damage.

However, the intent was to mean that the zombies are capable of absorbing more damage, meaning they have higher HP.

To clarify, one could either say the nightmarish zombies have more hp, and/or they have higher defense, therefore they take a relatively greater volume of bullets to kill (compared to their non-NM counterpart at the same level) and you end up spending more in ammo.

Of course, with ammo contract, you can earn $1M worth of special ammo in under 5 minutes for your red or black rocket launcher.
