The picture on the right is one of the common situations you may find yourself in where the corner piece is in the correct spot in the TOP LAYER, but the colors are not right. In most cases though, that first example won't always happen.
It's already solved!! Congrats you lucky dog you! The picture on the left shows the best case scenario for your corner piece. There will only be 4 of these pieces as well. Since we began with the white side, we will now be looking for the WHITE corner pieces, which have 3 colors. The next portion of solving the Rubik's Cube will be the top side CORNERS.
