Is there any human alive who could beat a gorilla in these conditions?

Round 1: Human has only intelligence advantage without tools. I don't think anyone can do it, but there is small chance someone with insane strength, stamina and speed blinding gorilla with his hands and excessively harassing him, leading animal to death at some point, but in this case fight is in small area so no one can.

Round 2: Someone who has knowledge about Gorilla anatomy. He/she/heli must also have high agility and strength. With sharp dagger(s), someone fast and strong can do it. I guess Navy seal or GSG9, GROM, etc. operatives can do it.

Round 3: Take someone fast, smart and agile, give him rapier or katana and Gorilla is dead. I see comments underestimating melee weapons, but well made sword is more than enough to kill most animals in right hands. Spear can work too so human wins most times.

Round 4: Any human with knowledge how to fire a handgun can 10/10 gorilla. Even average redditor like me can do it with 9mm pistol. All you need is decent aim and nerves to shoot. You won't even need short range melee weapon.
