How does Nikon coolpix p530 photography show fuzzy texture? See supplementary questions.

First of all, the image sensor of telephoto camera is too small, which can basically be considered as wide-angle imaging. Technical conditions restrict this kind of camera from obtaining the large-scale shallow depth-of-field effect (that is, the general background blur effect) like large-size sensor cameras such as SLR micro-single.

Technically speaking, the greater the focal length, the closer the close-range object is to the camera, the farther the background is from the camera, the larger the aperture and the shallower the depth of field, that is, the more blurred the background. You can try this, find a place where the background is far away, people or scenes are as close to the camera as possible, and then adjust the aperture to the maximum with the acceptable maximum focal length (the lens zooms to the acceptable maximum position) and aperture priority mode (this camera does this).

As for the photo being deliberately blurred, that's easy. Just use the manual focus mode. P530 has this function. Just deliberately adjust it to the out-of-focus position.
