It depends on the species of snakes.
Many venomous snakes have a low sensitivity to their own venom. For example, the blood of vipers contains substances that block the action of their toxin. Cobra venom affects specific receptors in the prey, however, in the receptors of the cobras themselves, there is an additional sugar molecule that prevents the toxin from binding to the receptor (although large doses of their own venom can pose a danger to these snakes).
On the other hand, rattlesnakes are fully sensitive to their own venom, so they try not to use their venomous fangs in conflicts with their kin.
Moreover, all snakes are sensitive to venoms that are different from their own. Thus, the largest venomous snake in the world—the king cobra—primarily feeds on other species of snakes, including venomous ones, killing them with its venom.
