Pro photographer are probably the only one that do not care about this, as they have another option (their very expensive and capable pro camera).

Everyone else takes photos with their phone and yes, everyone wants to take better photos

Pro photographers aren't professionals because they have expensive cameras, it's because they get paid to deliver professional results. A phone camera can be the most usable camera for a result because it's smaller and fits in more places.

Though the camera isn't even the most important equipment, that's lenses/lighting (plus stabilizers, studio backdrops, etc.)
