Nope. They found a marker on Cobra DNA that is slightly different from the same marker found in mammals. That's the marker that the toxin in the venom latches onto. When they spliced this marker into mice, the mice became immune to venom too.

Another Cobra did manage to bite itself. The bite became infected but the venom did nothing.

Also, many snakes without venom have immunity to those that do especially if they are found in the same region.

There are 27 hundred different species of snake (that we know of) so it won't be true for all of them but for the main venomous killers it's already settled science.
