It’s not really a difference in English, either. “Venom” is a specific term, but “poison” is general, so too with poisonous.
I think it’s specific in some scientific areas, but insisting on that is like insisting on calling a tomato a fruit, or a banana a berry.

Killer: actually, they’re red-necked keelbacks, so they’re both venomous AND poisonous!

My even-more-pedantic take is that poisonous is correct, but imprecise. There’s lots of ways to be poisoned. Ingestion, inhalation, dermal contact, and, yes, injection. But it’s all poison.
A poison is a harmful substance. A toxin is a poison created by a living organism. A Venom is a toxin that’s delivered subcutaneously.
Poison is the parrallelogram to venom’s square.
