This depends, if your image contains a lot of flat colours (like a screenshot of a website) then PNG can actually give you smaller file sizes than lossless webp. But for most images (especially ones with compression artefacts) lossless webp gives smaller sizes.

But that’s not got anything to do with quality. That’s compression size
Lossless encoding, by definition, won’t have any quality loss.
Watch some startup “invent” a revolutionary lossless format that discards some information.
Xerox did that ages ago.
