Official statement

Having no-index pages does not affect the crawling ability of the rest of the site, unless millions of pages need to be crawled to discover the indexable pages. The ratio of indexable to non-indexable pages is only important for technical volume reasons.

TL;DR

No-index pages do not impact the site's crawling unless there is a massive volume. The ratio of indexable to non-indexable pages is mainly significant on larger sites. This has technical implications only in certain contexts.
