What does quantity is not quality means

Quantity is how much you have of something. Quality is how good something is. It means that they are not the same. Just because you have more of something doesn't mean it's better. Example: There are McDonalds everywhere. McDonalds is not quality food, but it is quantity since there's so many. Chick-fil-a is not everywhere. There's not as many as McDonalds. Chick-fil-a is quality, and not quantity.
