It is of no use If you only know vocabulary and grammar and don't know how to use them.
It is of no use で「役に立たない、意味がない」という意味です。
only know vocabulary and grammar で、「語彙と文法を知っているだけ」となります。
この場合のonlyは、knowという動詞を修飾しています。
つまり「知っている」だけ、ということですね。
know only vocabulary and grammar とすると「語彙と文法しかしらない（だけ知っている）」となり、意味が変わってきます。
副詞の位置には気をつけましょう。
No matter how many English words you know, it's meaningless if you can't use them.
No matter how many English words you know, it's meaningless if you can't use them.
「いくら英単語を知っていても、それを使えないのでは、意味がない」
