It's a question of terminology - if you deposit a dollar in a bank, that adds to its reserves (the dollar), and its liabilites (the future dollar and potential interest). The bank wants to make a profit, and legal requirements mean it can invest in risky bets (such as loans) only to a certain degree - but that's still well in excess of 1-1.
In effect, your deposit is directly, causally linked to the ability of the bank to keep more interest _earning_ loans on the books; i.e. your deposit helps back those loans, and were it not for deposit insurance (assuming your account is below the limit) you would be on the hook for risks the bank took.
Your deposits are thus both necessary, and (barring FDIC) risk-carrying when it comes to the loans the bank makes. Isn't that in essence "your" deposit being lent out? If not in a literal sense; then at least what's the value in emphasizing the distinction?
