No that figure is the study being transparent on how it controlled for imbalances of selected input conditions showing raw numbers then the post processed reweighting of the samples. How does that fail as a way to account for differences in those conditions?
What would be your preferred technique of accounting for the differences of characteristics in those groups?

This paper is discussing small differences in small numbers, and the single biggest difference between groups is the baseline level of health for the study participants. About the only thing you can say from this is that old, sick people are sicker after Covid-19 severe enough to put them in the hospital.
