The small gear on the derailleur is rubbing against the freewheel, what could be the problem?

Typical. I see this a lot. These derailleurs are kinda junky and don’t have a real b-limit adjustment. I think you just have to live with it OR shorten the chain if this is a one by / in the largest ring up front.
Give the b tension screw a couple turns clockwise.
Mhm too big cassette/too small cage
Lube
look up park tools video on setting up a rear derealiur.
Does it rub if you place the bike on its wheels?? The B screw on this kind of derailleur does absolutely nothing to prevent that. I guess the only way you prevent that is by reducing chain tension by adding one link to make the chain a bit longer. Also please check if the derailleur is properly installed on its hanger.
They need some lubrication! The whole drive chain, then look for other issues!
B screw. Tighten it up my dude.
Lack of lubrication is the largest problem.
