CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.68% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 52.0% of scored records. A rank, not a probability.
NVD base score
