Prince Harry (or any Royal) only receives funds from the Sovereign Grant if they perform Official duties on behalf of The State. Then it funds travel, wardrobe, room and board while away. No income.

Prince Harry does have his own wealth inherited from his Mother Diana, Princess of Wales’ Estate. He is likely also the recipient of Private Trust income from ancestors on both sides (Fermoy and Royal Families etc…), which are not public record.

The Prince of Wales receives income from the Duchy of Cornwall Estate, which he shares with his immediate family (Camilla, Duchess of Cornwall, the Duke and Duchess of Cambridge, and Prince Harry). Prince Charles funds their official expanses related to office staff, wardrobe, and travel for Official Royal duties and charitable endeavors, but they must fund their own private life.

All you have to do is google “civil list” to find reputable sources for this info. I don’t think your net worth for Prince Harry is correct, I don’t think it’s possible for anyone to provide an exact estimate of what he is worth.
