Everyone in this table entered a judged powerlifting meet. They are not a sample of gym-goers and they are not a sample of the general population. People who compete in powerlifting have self-selected for being strong, have usually trained specifically for a one-rep max, and lift under competition commands — which is typically harder than the same lift performed in a gym.
If you have never competed, your comparison point is not the 50th percentile here. A more honest reading: this tells you what strong, specifically-trained women at your bodyweight actually do.
We publish no figure for the average woman in the general population, because no comparable dataset of measured one-rep maxes among non-competitors exists. Numbers of that kind circulating online generally come from user-submitted app data, from estimated rather than measured maxes, or from tables with no stated sample. Full method and limitations.
