In the way that language is commonly used, yes. People have been using it wrong for so long "jealous" has effectively become synonymous with "envious". Even if I dislike and disagree with it being used this way.

If someone is eating a donut and you say "I'm so jealous [of having the donut]" I'm fairly confident most everyone would understand you mean envious by definition but are using the word jealous to convey that meaning.

And nauseous vs. nauseated.

How dare you!

Actually a lot of venom is perfectly edible so long as you don't have a stomach ulcer or cut in your mouth or something.

Yep, and even when talking about living things it's not a clear distinction.

In biology, poison is a substance that causes harm when an organism is exposed to it. Venom is a poison that enters the body through a sting or bite. In a bunch of medical fields though, poisons only apply to toxins that are ingested or absorbed through the skin and that definition sometimes carries across to zoology.

Venomous creatures are poisonous by most definitions because venom is a poison. But if the distinction is useful in a medical or zoological context then they're not.

tldr: The pedantry of eg. correcting someone who says a snake is poisonous is totally pointless and mostly wrong.
