This is simply untrue.
It's true that at one point simply getting everything into focus at the right moment took a skilled photographer. But that was never the sum total of what a skilled photographer brought to the table.
A sunset photo isn't good simply when it's the best of a million possible photos of a sunset. It can be good because the photographer found an interesting location to set the picture. It can be good because the photographer waited-for and/or was present for an opportune confluence of elements such as weather, tide, etc. It can be good when the position and angle of the camera framed the scene in an appealing way, including or excluding other elements to enhance the shape, color and symmetry of the composition. It can be good when the focus highlights an interesting subject, and de-emphasizes non-essential visual noise.
Taking a billion photos can guarantee that you get a solid reproduction of whatever you pointed your camera at. But it will never render irrelevant the skills of subject identification, color balance (artistic balance, not simply accurate reproduction), composition, framing, etc. And lastly, it's absolutely no substitute for inspiration, education and experience.
