I would doubt that even most Nobel laureates would qualify as 1 in 100 million. There are nearly 1000 living Nobel laureates out of 7.7 billion, so the rarest they could possibly be is about 1 in 8 million.

Additionally, Nobel Prizes only cover a handful of fields out of hundreds of possible fields people could work in. I would put it at more like 1 in 100,000 or 1 in a million.
