Marketplace Licence

1-Are all contents in the marketplace have the same licence meaning i can use them as i want in a COMMERCIAL project? so to be sure this will also apply to mixamo animation pack and Micro monsters and hero’s pack?
and also Gametexture material pack?
2-Any pack who is free/commercial can be used in a commercial project without giving notice to the sellers of these items ?

Thanks and best regards.

Hello,
this sticky thread is really interesting : Marketplace Info and Guidelines: READ FIRST - Marketplace - Unreal Engine Forums
especially with this link : https://www.unrealengine.com/marketplace/marketplace-business-terms-faq where you can find : What can users do with my content once they purchase and download it?
