Its not the gear!
Well, sometimes it is. A wildlife photographer in a hide without some long glass is going struggle. Wedding photographers likely need a fast wide angle and standard lens for low light and group shots, a general zoom in the 28-105mm range.
Street photography was once ruled by the rangefinder for the reason of the viewfinder seeing wider than the lens, you could see the picture develop and people moved in and out of the frame. An advantage that also the Fuji X100 has.
So yes you need the right equipment to do the job. I know of an amateur photographer that fell in love with the Leica Q2, used it for everything, and gradually went professional and started to specialise in watch photography. The Leica Q range, while an amazing camera, possibly one of the best compacts money can buy, closely followed by the Fuji X100, Ricoh GR, and the much missed Sony RX1; is not exactly a camera suited for that style of photography. So it was changed to a full frame Sony mirrorless and some macro lens. A tool for the job but not the heart.
There are cameras out there ideally suited for particular duties, then there are those that inspire, spur creativity and drive ones passion forward.
