I would argue that 100 of almost any creature with some semblance of fighting ability would win. I'd have questions about whether a gorilla could even fend off 100 wasps. I think a more reasonable question would be whether or not 10 people could beat a gorilla. That's not enough to win by simply wearing the gorilla out, but it might be enough to ensure they can develop a plan to encircle and bring the gorilla down.
