I'm confused by your question.

While some "envenomed" bites are fatal or at least quite serious, not all envenomed bites are...Anybody know what percentage of envenomed bites are fatal?
Envenomation itself appears to vary remarkably, as different species do not envenom equally; further, it appears that even the same snake (let alone the same species) may envenom more on one bit than another. Many bites go unreported, so the percentages are skewed if the victim survives ("non-fatal").
I guess we should only worry about how many people don't survive the bite, whether they were treated or not. I would assume that 100% of fatalities were envenomed.
So that's a fair question, to which we may get no answer. I have a source here vaguely attributing this to the American Red Cross (but) that only 20-30% of venomous snakes put any venom into the bite. That's for a pit viper, although the guy's accompanying photo is of a rattlesnake. So I'm not sure he's reliable.
eMedicine discusses a few species, and says that envenomation is...
- between 50-90% for diamondback rattlers
- between 33-45% for cobras
- about 60% for Australian browns
- unknown for US coral snakes (low morbidity; most cases go unreported)
- unknown for copperheads and moccasins
- unknown for the mohave rattler
Obviously, that's a big range with a lot of guesses. Sadly, I don't know how much of this is reliable.
But what US percentage of reported bites are fatal? There are 4,000-7,000 bites reported to hospitals/poison control centers/paramedics each year. On average, only 4 people die each year. Picking 4,000 as the lower number, the percentage is 0.1%.
No international stats exist.
