The z-score method (often called standardization) transforms the info into distribution with a mean of 0 and a typical deviation of 1. RV object holding the given parameters fixed. If you actually want to see "how many have the same count", rather than a representation of the disribution, then you'll either need to set the bins kwarg to be df["count"].max()-df["count"].min() - or do as you said and count the number of times you get each count and then create a bar chart.
