Smaller yes, drastically smaller, not necessarily if you want to keep equivalent image quality. Tried with this image:
Exported as Jpeg: 185K, as WebP: 137K. (used Q=90 for both, whatever that means). So this is about a quarter smaller in WebP format.
Then you have to understand that all these lossy compression schemes are data dependent, they work better on uniform and clean areas than on noisy ones. In the Webp export dialog, you can indicate the type of document and this may influence some compression parameters. In the Jpeg export dialog, the "chroma subsampling" in the advanced options is the main factor for the output size. Color information can be stored as a half-size image (one fourth the pixels) and this alone divides the total size by two (there is also a chroma subsampling in WebP, but this isn't an option you can tweak).
