Not entirely wrong but not entirely correct either.
It all depends on the way the PDF was made. One can make a scanned image of pages and then have OCR recognition done on the scanned text (which is essentially an image). Then, underneath that layer of image is plain text.
Another way is that the text itself actually is text and not an image. In this case, there would be native font embedded into the PDF. This is the preferable method.
