Making use of Marketplace content

Okay, this has bothered me for quite a while. Can I or can I not use the free materials provided by Epic Games on the Marketplace in my projects? How does it differ in non-commercial and commercial games? I do not want to waste your work, Epic, but I am just very lazy.

Everything made by Epic can be used in your projects non-commercial and commercial if these are used with Unreal Engine (not other engines). All these are pretty much stated into the EULA you agreed in using Unreal Engine and also the Marketplace FAQ states about not just Epic’s content, but also other sellers.

Thank you!
