In warmer climates they could but there probably wouldn't be enough food for them to thrive.
Crocodiles and alligators thrive in tropical and sub-tropical climes, they need warmth. They are large animals and need enough food to both expend the energy to get more food and to just survive. The sewers of most major cities aren't quite warm enough and only offer small rodents for the most part.
The urban myth stems from people flushing unwanted pets down the toilet. Because most septic systems aren't equipped to deal with large masses such animals would die and, if large enough, clog the system even if they are only very small babies.
Obviously any decent sized alligator or croc would never fit in a toilet.
Also obviously, such animals would have much better chances in any near by lake, pond, river, or stream and would leave the sewer in search of better hunting grounds rather than starve to death. If it's a cold place the sewers would be little better than said natural body of water. They are reptiles and, thus, cold blooded. They need warm environments to keep from dying of hypothermia.

Same reason alligators can't. Not enough sunlight.

The tough city rats gang up on them!
Sorry for the silly answer.
I suppose if the crocodiles/alligators adapted to the environment they could. A very long time ago, I had a paperback novel titled "Night of the Toy Dragons", which dealt with a mutated breed that did adapt. It's feasible I should think since there would be lots of rats.
You could have a movie marathon with the number of alligator films, all saying that very large creatures can live in the sewers.

cuz rats are small and faster than their jaws so they die of hunger and also die of illness caused by dirt and if some survive we kill them cuz of fear...

Because they will get too big for their environment, they will not have enough sustenance, and the climate isn't favorable...
As you can see, they have lots going against them
