No, most decent digital cameras automatically attach metadata to the picture. Metadata is information attached to the file, but not visible in the picture, things like; the type of camera, resolution setting, F-Stop, shutter speed, whether flash was used, etc. Most cell phone cameras don't attach this info.

This picture doesn't contain any of that info. So, either it was taken with a cell phone or the metadata was removed, intentionally or not.

But, without that metadata, there's no way to tell what the original settings were and whether the picture was manipulated.
