I’ve heard people say that even if a billionaire tried to liquidate all of their net assets, their net worth would drop dramatically. Is this true, and if so, why?

Let's say you own $1B worth of stock in a company (that's a lot of stocks). It's not as if you have $1B, your wealth is tied up in those stocks and only available to you as cash if you sell those stocks. The price of those shares is determined by supply and demand. If you you try to offload all of those stocks at once, the supply of the stock will shift substantially, causing the value of the stock to drop. As a result, once the stocks are sold you will be left with less than $1B dollars.
