How to change skewness into a percent

I saw your ask the wizard question on skew https://wizardofodds.com/ask-the-wizard/video-poker/probability/ , where you explain why playing JOB you will not win very often if you play a couple of hours at the game. This is the game 9/6 Jacks with a progressive royal (4607 ave). progressive SF (342 ave) and progressive 4 of a kind (use 130 ave). WinPoker give this game a long run 100.2962% with a varience of 26.33498. If you play 4000 hands per session going forward, what is the skew and what percent of the time will you actually win a session? I know from the last year that I just don't win without at least one SF.
