"Reading a hundred times is never too much, and editing has new gains" is not a poem, and it is not accurate to say famous words. It should belong to a proverb.

Proverbs are just fixed sentences circulating among the people, which reflect profound truth in simple and popular words.

Famous sayings are famous statements, which are widely circulated all over the world.

Poetry is a sentence that constitutes poetry. Usually, according to the format and style of poetry, the number of words in each sentence is limited.

I hope I can help you!
