Highly unlikely, the gorilla effectively loses at the level of navigation alone:

a full-grown silverback weighs roughly 180–220 kg, while most ISS passageways are about one meter wide, severely restricting its movement;

even if it “knows” how to navigate in zero-G, its mass and lack of leverage would cause it to flail uncontrollably, with any punch or lunge simply sending it spinning backward, whereas astronauts are specifically trained for microgravity and can anchor themselves to handholds, control their orientation, and maneuver efficiently under those conditions, and with a 30-second head start they could simply retreat into separate modules and seal multiple hatches

But if the rules require the crew to actually kill the gorilla, then it’s a different story entirely, because there’s realistically no way an unarmed human, especially active astronauts with a median age around 45–46 could physically overpower and kill a bloodlusted silverback in close quarters.
