It's almost the same case as with Lee. Being a failure in one area doesn't necessary mean you can't be a prodigy in another. I mean, Lee has no talent in ninjutsu or genjutsu, but Kakashi admitted his genius after seeing his ability to open 5 of 8 Gates. Also, shadow clones aren't really about the numbers, numbers only indicate the chakra reserves of a person, with Naruto having huge reserves and Boruto having less formidable ones. SM/Kurama combined use isn't also that of achievement, Naruto just didn't realise they could be used simultaneously, particularly because of Kurama rejecting Fukasaku's attemps to fuse with Naruto.
