My site lost 60% in January update, I checked GSC and noticed same thousands of spam links. I then went ahead and disavowed all of them from domain level, but my site still got hit in may update losing 30% further. I even updated all my posts (450 pages) changed title and description, reduced repetitive headings with target keywords. Now site is shit, down and flat. Recieving the lowest quality of traffic.
So, in my opinion, I don't think disavowing spam links changes anything. The best thing is to continue updating your site, create new sites and make more videos.
