Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
Please note that Google crawls the sitemap and website according to the crawl budget of the website.
The lower number in Discovered URLs that you see in Google Search Console just means that the URLs in the sitemap were already found by Googlebot by other means, instead of via the sitemap. For example, Googlebot may have found the URLs from internal links or possibly from links on another site.
However, please ensure that the sitemaps are excluded from caching:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
It is completely up to Google if they want to index or not index your website. So, if you haven’t willingly or accidentally made your pages noindex and Google still isn’t indexing your pages – it means that either Google doesn’t want to index or hasn’t crawled your post yet because it hasn’t allocated that much crawl budget to your website.
Please check this website for more details.
Looking forward to helping you.
