Wrong.

Digital images have a fixed amount of information in them, which is
determined by the number of pixels. Each pixel is a solid color; no
sub-pixel information exists in the image.

They are not made "mathematically." When a digital image is enlarged, it
still contains the same amount of information. No new information is
added. No new information exists. The same amount of information is
spread over a larger number of pixels, that's all.

Some non-critical viewers who do not know how to evaluate image quality
are fooled if the resulting upsampled image is over-sharpened; they do
not know how to see the results of the interpolation, that's all.
