Not neccesarily. If 1% of those 100% own 100% of the wealth, and 99% own 0%, they would still collectively own 100%.
If you had 2 blocks with 50% each, and they both filled 50%, everyone would be equal, because if a few had more than the rest, they would enlarge the top half.
In any case, 100% are bound to own 100% of the wealth.
