An AAPL share represents about one five billionth of Apple. Tim Cook owns about 1.7 million of those - so Tim Cook owns about three hundredths of one percent of Apple. Jobs died with about 5.5 million shares, call it one tenth of a percent of Apple. So the value of the shares of Apple which don't currently belong to Tim Cook and the Jobs estate (no idea if they still hold those shares) amount to at least 99.9987% of the value of Apple.

Using your assumptions, the math comes to 99.87%. (Your excellent point remains, of course.)
