Is it still true that 3xx redirects don't cause you to lose any ranking?

In this: https://moz.com/blog/301-redirection-rules-for-seo it says that simply redirecting - provided you don't change anything on the page - isn't going to cost you rankings. Is this still true, or is there any new data/case studies that have been done since? I haven't seen anything updating it and just want to make sure because it's from 2016.

We want to do simple 301 redirecting without any changes to the page.

Or has anyone had an opposite experience?

Thank you so much!!!

Yes, 301 redirections are still respected and should pass all "page rank" (if page rank still exists). If you're doing a site migration and plan on using 301 redirects for a high volume of URLs, it's not uncommon to see an initial drop in rankings as Google re-evaluates the site. Don't panic if that happens, you should return to normal as the only thing that changed is the URL.

Be very careful as 301 redirects can be costly if executed incorrectly. Make sure to check the redirects with an HTTP status code checker.

Redirects do not affect ranking, only in case when they are used in a wrong way. 301 is more preferable.
