If you look here:

Bill Gates is only the 5th richest.

…but the Bill & Melinda Gates Foundation has an endowment total of $75.2 billion.

So, his wealth ($149 billion) + foundation ($75 billion) = $224 billion.

So, my question is…can he spend that foundation money any way he wants instead of spending his personal money? If he wants a jet can he just use the foundation money? If so, then he is still the richest person in the world even though he does not get labeled as such in the news anymore.
