Because surface would imply these planets have a rock surface. They don't. They're mostly gas. They do have a core, but that's another matter. Jupiter, the largest gas giant, has a really small core for its size, Saturn has a core many times the size of Jupiter's, so it would be misleading to refer to a gas giant's core as its surface, because it would make Jupiter's "surface" smaller than those of Neptune, Uranus and Saturn.

Uranus is believed to have a rocky core, but it is impossible to image. Jupiters core is suspected to be entirely liquid hydrogen which if we somehow could send a probe that far in and not get crushed with the weight equivalent to an ocean 10,000 miles deep and no light it might appear as a giant shimmering sphere of liquid mercury. Saturn is such a puff ball of gas that if you found a body of water big enough it would float-being the least dense of all the planets. So surface really can't be applied to any of these.

Gas giants in our solar system do not have a solid surface because they are made up of gas.

And where would you declare the surface to be for a blob of gas?

Impossible to define.
