Yes,there is only one poisonous species in the world named Heloderma inhabiting Central America.

Answer

Incorrect. There are two poisonous lizard species in the World: Gila Monster, and the Mexican Horned Lizard.

The real answer

no there are two the Mexican beaded lizard and the Gila monster that's the right answer

That is actually incorrect as well.

There are 3 lizards that contain posion glands. The Gila Monster, the Mexican Bearded Lizard, and the Komodo Dragon.

Originally the Komodo Dragon was thought to kill its prey using The bacteria in their mouths. But just this year we were able to dissect and identify that they do indeed have poison glands in which they use to kill.

incorrect again the komodo dragon is not poisonous on the Gila monster and something else i forgot lol

There are about 1500 species of lizard that have poison glans. The komodo was thefirst to be identified, except for the commonly know and mentioned two. After that about 1500 species have been confirmed to have poison glans. they were evolved a long time ago and many species lack a means of utilizing the poison and usually the poison is very weak. snakes took a step forward on the lizards with their fangs.
