You can use this asset for personal and comerciall purposes, but you not allowed to re - distribute or re - sell the asset or any part of it (even if modified).
then you cant legally use it commercially as if its in a game you distribute its a violation see how you need to say "redistro by itself or resell on its own as your own"
I believe what they said was that you can use it in your game and sell your game. What you cannot do is to build an asset pack including these assets and sell it that way.
