how does nick's statement "you are worth the whole bunch put together" show a chance in nick from the beginning of the novel?

After his “privileged glimpse into the heart,” a journey he does not wish to repeat, the story turns to Nick’s perceptions of Gatsby and of Long Island. Gatsby’s dream almost replicates that of the “Dutch sailors,” who, in their discovery of the New World, found a latter-day Camelot. Such a similarity justifies Nick’s belief that Gatsby’s dream made him “worth more than the whole damn bunch put together.” He had “an extraordinary gift for hope, a romantic readiness,” that almost justified his illegal doings in the eyes of Nick.
