Poison is generic. Venom is specific to normal method of delivery (e.g. snakes and bees).
Swallowing venom may or may not hurt you. Probably not a great idea, but there’s a better chance you’ll be okay.
Getting a known poison stabbed/injected intravenously seems likely to be pretty effective, but it depends on the mode of action. Blood goes everywhere in the body, so it will likely find its target eventually.
I think the voiceover was added for YouTube, but I’m pretty sure that footage came from a game in 1991 “Zero Wing”
