Here is my solution:

let navigationLinks = document.querySelectorAll('nav a');
let galleryLinks = document.querySelectorAll('ul#gallery a') ;
let footerImages = document.querySelectorAll('footer img');

Rodrigo, you wrote "sometimes all wee need is to see someone else's code to understand the problem." Perhaps, but it could still be accompanied by an explanation. This is a Treehouse policy, not mine (but I think it's a good one).

Also, this solution works but is overly specific. Since ID's are always unique, it's never necessary to use both the ID and the tag name to select an element.

saying query selectors accept elements, ids, and classes, but not giving a single example of it being done like this in the videos and then expecting us to figure that out is ridiculous imo

let galleryLinks = document.querySelectorAll('ul#gallery a') ;

Hello, can any one explain to me how this code works. Thanks

Note that's the one I pointed out as overly specific. It's not a good example of a solution.
