When they speak of Creditors in reference to the FTX scandal, what does that mean?

1. Are they people who loaned their wallets to FTX? In other words, FTX/Alameda traded with the coins owned by Tom Brady, for instance? I read there was a high interest paid back on those accounts, so Tom Brady received interest (on what baseline price)? Surely, the excess interest (over bank rates) should have accounted for the Higher Risk. How was that interest rate determined?

2. Presumably, the wallets held at FTX but not involved in this loan scheme are safe, right?

Hoping that some of you know more about this - thanks.
