3.The sensor size doesn’t have any direct effect on the depth of field.
However, as APS-C and smaller sensors have the effect of altering the field of view of a lens, shorter focal length lenses are used in order to get the same field of view as a traditional full frame camera, therefore the depth of field for a given field of view will be greater.

Not entirely so = larger sensors tend to have smaller pixels, which affect the circle of confusion and therefore the perceived range of acceptable focus. Perhaps a minor factor, but nevertheless one to consider along with the other comments.
Regarding the longer lens, based on my experience with a 70 - 200 f2.8, that background would have been very blurred at, say f2.8, provided that you had a reasonable distance betweeen the camera and the subject.
