I've pre-ordered many times and very rarely am I charged in full before the game launches.

I pre-ordered pokemon Sword & Shield from Best Buy a few years back and was not charged until I picked up the game. Same thing when I pre-ordered Scarlet and Violet. Didn't charge until the order shipped.

Also source: me. An accountant. Sure you can see units pre-ordered but the company cannot report prepaids as revenue until the order is fulfilled.
