That’s possible. Not all physical damage on a computer is visible to the naked eye.

If your computer has a selective USB suspend setting, try turning it off.

Alternatively, try pulling the battery out, holding the power button for several seconds to drain all power from the machine, then putting the battery back in and seeing if that does anything.

Try to boot up an OS with a USB stick on a usb port you know works and see if the USB C ports start working. If they don’t, it’s probably a hardware issue. If they do work, it may be a driver issue.
