Yes. There are roundworms of different species that can infect humans and they can cause serious health issues. Roundworms common in puppies and kittens are some of the roundworms that can infect humans which is why it is important to treat puppies and kittens for parasites early and as often as recommended by your veterinarian.
liver fluke-tape worm
The animal has to actually have the roundworm for this to potentially occur. If you are unsanitary and never wash your hands then yes. This is especially true after you clean litterboxes or pick up after your dog. If you allow your cat to walk all over your kitchen counters and dining room tables where you eat, then you can certainly expect it.

This is probably the genus Ascaris. However, there are very few roundworms that can infect both pigs and humans, and these are not common in the developed world.
Endoparasites: Live inside the host eg. Plasmodium, Tapeworm, Roundworms, Bot fly ect.
Many parasites, such as various types of worms, are highly opportunistic, meaning they will infect any warm body they can get into. I have never heard of "wolf worms," so cannot tell you for certain if, like tapeworms and roundworms, these can also infect people.
