Nope. Gerrymandering makes districts more or less homogenous in a way that benefits one party. To tilt a balanced state Republican, you concentrate Democratic votes into a few districts where Republicans will never be competitive, then create a larger number of districts where Republicans can consistently win with razor-thin margins. You'll have one homogenous district that is 70% Democratic, and seven Republican districts that are 53% Republican.
