Short answer:
Lenses and field of view.
Long answer:
Your eyes work very much like a camera, with field of view for binocular vision at about 115 degrees.
According to this site, the true central focus field of view is around 40-60 degree. Now pulling out another site that I found here, you can see that for a normal AFS-C (DX format) sensor, around 20-30mm fits the field of view of the eyes. The images here are more natural to look at.
Now for your case, the videographer has chosen to use larger sensor (likely for high-end professional device) or/and shorter focal length.
Now given the photo above, you can clearly see that you will feel that the place is larger when you have lower focal length, which in turn have a larger field of view.
The stadium is especially photograph/videoed in such a way that it will feel magnificent, so that it will grip the viewers attention. As your question said, the player seems need to be very good to hit the cricket balls out of ground, and this makes the show more entertaining.
And without proper depth of field, your eyes trick you into thinking it's really huge.
Edit: How depth of field changes everything.
Picture on left shows more distance separation, making the model plane smaller; picture on the far right is very flat and the whole thing seems bigger.
Picture shows how manipulation of depth of field can make stadium look like a miniature toy.
