True Statistics?

The AP says that about 1,500 climbers have made it to the top of Mount Everest in the past 53 years, and some 190 have died trying. Is that possible? If so that's almost as exactly as bad as playing Russian Roulette (1:7).

Of course the 1500 doesn't include all those that have tried an failed. I wonder what that number would be.

I also wonder if the Sherpas are included in this statistic. I sure hope not.
