    what does it mean by Mask?
    is it greyscale albedo detail?

    Detail mask part (blue channel in mask texture) describes which part your UV's get used in (optional) detail mapping. HDRP docs are bit lacking on explaining this but you should understand the application if you read the old standard shader docs that explain the purpose and usage of detail maps and mask:
