Why TV actors arent given fair chance?

TV actors work ethic and professionalism is much better than these BW actors especially the nepo kids so my question is why dont they get fair chance in BW movies? Most of them have amazing acting skills and popularity as well so why dont producers take a punt with them rather than having nepo kids? The reason I respect Sushant is cause he's a TV actor and took the tough route rather than offering his body to producers and then get a role in movies.
