Via bleeding out to death or passing out from the sheer pain sure, but you don't know where that snake's fangs were in (usually it would be a dead animal (ex, its prey)), but there are such thing as non-venomous snakes or "low-venomous" snakes that aren't big enough or potent enough to kill you.
But either way, if it were to be a generic venomous snake that bit into his balls, then yes he could die before getting any other complications.
