The fact that your page is not identical to what the video shows, does not mean the same approach cannot be applied. You can try looking into it and see if there are ways in which you can do that. For example, if your web page URL has the page index, you could also simply build the URL with a new index and use Go to web page action each time you want to open the next page.
The main idea of the video is on how to build a table that you keep appending new values from each page to, instead of expecting the Extract data from web page action to work properly with the pager functionality.
All sorts of options are usually available, but it is quite difficult to comment anything without knowing and seeing the web page.
