commercial licenses

Hello everyone, I have a question. I’m an indie horror game developer, and I don’t have much experience with 3D modeling, so many of the assets in my game are from the Unreal Marketplace. Here’s my question: if I use assets from Quixel Megascan or other developers that have a “standard license,” will I run into any legal or commercial issues? I also use Poly Haven, as I’d like to publish the game in the future. Sorry for the question, but these things just popped into my head. Thanks to anyone who reads this. Best regards.
