If you download a save file that originally contained worlds you don't own, you just won't get those worlds. You'll probably get a warning when you first go to open the save that you're missing packs, but you can just ignore that if it's a blank save. If you do ever get packs that contain worlds and go into that save after saving it without those worlds, they will no longer be blank--they will be the default world as it comes with the game.
If it's a save that has buildings renovated or sims added or made over, you would want to find a save that either only uses packs you have or that only uses the correct packs for the worlds/sims.
