It's very different. Pre-bankruptcy FTX would have owed crypto, so increases in crypto prices (other than FTX's own bespoke "token") would not have helped. Post-bankruptcy, FTX owes cash based on historical (lower) crypto prices. So no, SBF is not quite right.
They lost a ton of their customers' crypto. They're paying people back in cash at prices that are now 1/3 or less of the value of the crypto that customers deposited with them.
