In the movie yes but they are not supposed to be heroes at least not in the sense that they patrol and want to stamp out crime.

Even the Fred Wolf show which 90% did have them as super heroes would sometimes have the turtles not want to get involved as they're not vigilantes usually to set up them finding a motivation later (usually sensing Shredder's involvement).

They are heroes in the sense that they are the protagonists but Leibesman suggesting he got the vigilante aspect from the comics shows he didn't read them.
