They're just saying what is well-known: Nintendo is an integrated software and hardware company, which MS and Sony are not. Their focus is as much on producing compelling software to sell their systems as it is on producing compelling hardware to make software for. Microsoft and Sony, conversely, are more oriented on producing the hardware, and software is only secondary.
Simply comparing the overall libraries of games for a given hardware platform makes this obvious enough: there are more Nintendo games at the top of the best-selling games list for a given Nintendo platform than anything else, whereas Sony and MS first-party offerings barely register at or near the top of their consoles' respective lists compared to third-party offerings. Interpreting it beyond these hard facts and implying some form of arrogance or pompousness is silly, not to mention very un-Nintendo-like.
