Sitemap and Google

In Google help written, Its better to have maximum 100 links in each sitemap.
So does it mean that more links on sitemaps will not be indexed?
What does it exactly mean?
Can i have 500 links in a sitemap and google indexes them?

This is not true. Each sitemap can have up to 50.000 urls. For more you can use more files with 50.000 urls each.

Yes, I have been worried about this issue, fear of punishment google

google index more than 1000 of links.

According to my opinion, we should  have maximum 500 links in each sitemap within one month duration.
