Is Google Search Console data accurate?

Yes, the data of Google Search Console is accurate. The only reason I could think of having an inaccurate search console account is if your site was being crawled but not indexed by Google. If that's the case then your site will be appearing in search results, and in the webmaster console, but won't appear on the index. Google Search Console is a free service that helps webmasters and SEOs track search queries, clicks, and conversions from their websites. It also provides a report of the search results, showing you what people are clicking on and how your website ranks in search results.
