The venom itself is usually not specifically fatal, unless you have an allergic reaction (just as bee stings generally aren't, but if you're allergic you can die), or are punctured in the right spot, but there are enzymes that can cause necrosis (tissue death), and stings can also lead to infections which CAN be fatal.
I think the danger is relatively low as long as you take precautions not to get stung, and if you do, always seek medical attention immediately. At the least the wound needs to be professionally and thoroughly cleaned, any portions of the stinger need to be removed, and you will probably be given antibiotics to prevent infection. The location and depth of the wound will also determine severity. Always treat stings as an emergency. It's people that don't seek help immediately, or at all, that are at the highest risk.
