i uesd youtube free audio and blender for 3d model. in applying question, "Did you use any content you do not have ownership rights to?" do i have to write in YES or No? if license is free, the ownership is mine..?

i have two questions I build on mac os not ipad. Is it okay the version xcode13.3 on mac 12.3.1 ? Will my project be judged on xcode or be judged on playgrounds ?

Is it okay to use that version to submit ? the requirement is xcode12.3 + xcode 13.3 .

required: Xcode 13.3 on macOS 12.3 is it okay to run Mac version 12.3.1 not 12.3? playground book is not allowed to be submitted?
