this doesn't look like a brilliant move

It looks like a greek gift sacrifice. Look it up on the internet

How is it not brilliant? It's hard to know when to use the Greek Gift.

looks like a Greek Gift sacrifice

Kxh7 Ng5+ Kg8 Qh5  its very good move 

greek gift is brilliant if you use itwhen you are supposed to

move 33 white of post number 7 is also brilliant, as it wins a rook, and if black takes back, mate in 1

It’s not so hard if you study The Art of Attack by Vukovic. He explains the necessary conditions.

And a favorable review of that book here:  https://web.archive.org/web/20140708234424/http://www.chesscafe.com/text/aac.pdf

And the following is the first of three paragraphs describing when the so-called Greek gift sacrifice is a possibility:

Necessary conditions for the classic bishop sacrifice

White must firstly have a queen, a bishop and a knight. The light-squared bishop must be able to reach h7 in order to force the tempo of the attack, though it is not essential that it should put Black in check or take a pawn in so doing. The knight should be within easy and safe reach of the square g5, and the queen within reach of h5, though in some cases it is enough for it to be able to get to some other square on the h-file

Who is is for?  I can't vouch for the accuracy of the closing, but here's what the review says:

...it is difficult to imagine that this book would not help a player of almost any strength. So, what more can one say about one of the great chess books that has been reprinted a dozen times and that now appears in an expanded, improved edition? Thank you

Patzersreview closes with 

I would say that players with a rating between 1500 and 1700 will probably get the most out of the book. In A guide to chess improvement, Dan Heisman recommends it to players between 1700 and 1800. Either way, this is a book for intermediate players. It can of course be read by beginners, but I don't think it would be the best use of your time. You will need to have a fair understanding of positional play and tactical shots in order to understand what is going on in the book.

In the first screenshot, it is greek gift sacrifice leading to a strong attack for white, however, it isn't actually brilliant, it is somewhere in between 'good move' and 'brilliant move'. I think that's what chess.com is trying to do with 'great find' can someone confirm this?
especially with the second game, 33. Qxf8+ is a nice little tactic but not exactly brilliant.

oh, It's an actual book. Nice anyways and thanks

Of course its an actual book. That’s how people learn. I have the old Cadogan paperback, but I read the ebook version last spring. https://everymanchess.com/collections/training/products/art-of-attack-in-chess

John Nunn added some commentary in a few places to the new edition: ebook and print.

This “great” move is textbook Greco.
