Here is what Google Search Console says about my website:

In Google Index > Index Status: 161 pages indexed
In Crowl > Sitemaps: 52 pages submitted / 52 pages indexed

When I do a "site:" search, about 65 pages are listed (there are still a few old pages listed that do not exist anymore).

But, why such a large difference (161 vs 52?). It's going on like this for almost one year now. Does it imply that something is wrong with my website?

Thank you!!!

I didn't find the right solution from the Internet.
