Where you get your "assets" or "content" from is not as important as long as it's legal to use. If those sprites, music and so on are acceptable to distribute as indicated by them (either by including them as public domain, or by license) then I can't see a problem with using them if they work for your game's design.

Unfortunately, though I do have a copy of Game Maker 8 for Mac, I don't know enough about it's included content to know one way or the other from experience.
