Yes that is absolutely true, nicotine is not meaningfully toxic on its own as far as I'm aware.
That said, it doesn't mean it's not dangerous. For instance, Opiates were once thought of as a "perfect anesthetic" because they achieve the desired effect with little to no toxicity, but we've all seen how that played out over the last few decades.
Nicotine is quite toxic at moderately high doses, ask any farmer who works with nicotinoid pesticides, or any ER attending. Nicotine is a potent neurotoxin, it’s just that typical use from smoking and food falls below the threshold for poisoning your nAChRs receptors. However with vaping, that’s no longer the case, especially when people spill their vaping liquid on clothing or skin.
