There’s a huge difference between being rich (or wealthy, not the same) and simply having more than someone else.

No. That's basically the definitions of those concepts. They are relative to how well off everybody else is.
Cash can (arguably) mean paper money but there is often a distinction made in capital markets - physical cash is for retail banks.
An applied example of a cash position in finance is repo: You need some short term cash - a simple hack financial markets use to do this in an administrative/credit efficient way is to simply sell (say) a bond (the collateral), receive some money (your cash), then agree to buy the bond back tomorrow for slightly more than you sold it for (the interest rate).
