I’ve always been curious to what exactly this means. I may be overthinking it but like what does this refer to? Does this mean that they have can inject venom up to X amount of people before they die or run out?

Venom potency is normally measured as [an LD50 – the amount of venom mass per body mass that needs to be injected to cause 50% mortality](https://en.wikipedia.org/wiki/Median_lethal_dose).
When people say “enough venom to kill X people”, they likely mean that the animal’s venom glands contain a reservoir of venom with enough mass to give X average people a dose that large or larger.

Injecting that many people isn’t really realistic for most venomous animals, which typically seek to use their venom for hunting something smaller than humans or as a last resort defensive weapon.
