Unfortunately, having directly felt the brunt of Google AI deciding it needed to disable something about my account for no appreciable reason, this is simply not true.
Even if Google had reasonable customer support, relying only on a cloud backup is unwise.
UX being what it is, my aunt just lost most of her iCloud photos because she thought she was cleaning up her laptop to donate, but iCloud synchronized all the deletes up to her account.
My father "clicked the wrong button" and lost his entire Picasa library a while back.
If you aunt deleted her pictures recently enough, she might be able to get them back: they're stored in a Recently Deleted folder for 30 days before they're really gone.

More copies are better.
