mate... you still have to unzip it
just because 7zip lets you browse it without unzipping it doesn't mean it's functional, you have to right click, go to 7zip, and "export to (folder name)"- do NOT use export here when unzipping stuff unless you like potentially bombing an entire directory with loose files, or you moved the zipped folder to the folder you want the contents to be in.
If you're older than 12 and can't use a computer I implore to at least try to use google to learn
