To me it looks like your recovery USB flash doesn’t contain proper macOS Installer.
You have two options if you have any kind of network accessible Ethernet or Wi-Fi, use Internet Revovery with ⌘+⌥+R right after you press power button.
Or if you have another Mac available make new Recovery USB following this article:

Let’s see if you can boot up at least into macOS Recovery. Then go into menu, start Terminal and run ‘diskutil list’ or ‘diskutil apfs list’ and post output here.
Good luck...
