In a sense you are right and in a sense you are wrong.
Anyone can take random pictures of people on the street,with their phone or any other camera. I will grant you that.
However, that doesn't mean it's good and that doesn't mean it "captured a moment". Additionally, gear is *generally* required to emphasize a feeling or emotion in photo that a flat photo with no depth of field (in other words just an average photo).
Really good photographers CAN accomplish great photos even with the most basic of camera, but it isn't as simple as you are making it out to sound.
