Consequence. Crawlers have to discover every URL by following links. Pages that are deep, newly published, or poorly linked internally take longer to be found, and some may never be. A sitemap is the most direct way to hand a crawler the full list.
If that is not intended. Publish an XML sitemap and declare it with an absolute URL, e.g. "Sitemap: https://example.com/sitemap.xml". The line is global — it belongs outside any User-agent group and applies to every crawler.
Notice
Every URL is open to every crawler
The file declares user agents but no effective Disallow rule.
Consequence. Every URL is crawlable, including any that exist only for internal use. Crawl budget is spent evenly rather than on pages worth ranking.
If that is not intended. Consider disallowing sections with no search value — internal search results, faceted or parameterised URLs, cart and account pages.
