why should i study Rook endgames?

You could also call it a reference. This format isn't entirely uncommon in forums.

Without the link i would agree with you.
Using a link to a commercial platform is difficult in my opinion.

Is this link advertising?

I know - and he has > 4.000 posts in the forum. Strange enough but that is another issue.

"i almost never get that position in my games?"

• At rating 1622 you probably win or lose games from tactics.
  As you get stronger you will reach more endgames, especially rook endings.
  You cannot master rook endings in a hurry.
  So start now on rook endings, or be prepared to reach a plateau when you become stronger.

Rook endings will appear damn often in your games.

... Stop promoting other people's commercial products using links and calls for purchase. This is aggressive advertising.

Suggesting this or that specific product seems to me to be a fairly common and accepted practice at lichess. I do not call "for purchase". It is entirely fine with me if JustAChessPlayer177 gets the book from the library, gets some other book, relies on free online resources, ignores the whole thing, or whatever. The point was that an authority thought it was reasonable to do some LIMITED endgame study.

Exactly, and the degree of satisfaction might depend on HOW one chooses to "start". It might not go well, if JustAChessPlayer177 sets out to read Secrets of Rook Endings by GM Nunn, for example.

The link was to a free online sample. It seems to me that such samples are a valuable way to learn about what a book is like and how it may be different from other available choices.

I suppose that it would be fair to call me a kindaspongey former chess player (and current reader).

Remember, there ARE icebergs out there. If you want to discuss me or lichess practices, I would suggest that, out of courtesy to JustAChessPlayer177, you engage in those activities in some location other than an attempted discussion of rook endgame study.

Lets get to the point, i never reach rook endgames, why? and why should i study it in first place?

As I mentioned earlier, my guess is that the late IM Silman would have thought it reasonable for you to work through pages 1-158 of Silman's Complete Endgame Course. There is not a whole lot of rook endgame material - perhaps about 15 pages - really just a start.
If you progress to higher ratings, it would seem likely that opportunities to use such knowledge will arise with sufficient frequency to make it worthwhile.

"Silman's Complete Endgame Course"

• is neither complete, nor correct. There are better endgame books.

"Here are some excellent endgame books:
Chess Endings: Essential Knowledge (1993) by Yuri Averbakh ...
Silman's Complete Endgame Course: From Beginning to Master (2007) by Jeremy Silman ...
Understanding Chess Endgames (2009) by John Nunn ...
Dvoretsky's Endgame Manual, 4th edition (2014) by Mark Dvoretsky ...
Practical Chess Endings, 2nd revised edition (2018) by Paul Keres ...
At this point in your training, you probably only need to study one or two of these books to get everything you need. ..." - Learn to Play Chess Like a Boss (2019) by GM Patrick Wolff

Fundamental Chess Endings - Müller & Lamprecht is probably the best now.

'Dvoretsky's Endgame Manual, 4th edition (2014) by Mark Dvoretsky' contained some mistakes, corrected in a later edition by Müller
