It doesn't even prove that much.  There is nothing preventing a rogue
online shop from storing and reusing the CVV you give them.  Or selling
your complete card details including zip code, CVV and whatever.

In practice, the CVV is just 3 more digits in the card number. No
security whatsoever in that.
