How to interpret dotplot from enrichment analysis with gseapy?

Question

[bioinfo]

Hello,

I used gseapy for enrichment analysis and I am trying to understand the dotplot figure that is generated. This is what the object after enrichment analysis looks like:

Below is the figure they produced.

I am trying to understand what the % Genes in set represents. Is the percentage made from the Overlap column in the results? Does it mean that for example there are 19 genes in my list of gene that are part of the 87 genes in the IL-6/JAK/STAT3 Signaling pathway?

Thank you
