Very likely.I think it has already started last week, you can see the movement on October 13th at semrush sensor too.
I feel the same way, sadly...3 of my sites lost 15%-20% of the traffic. Amazon Aff on less than 5%-10% of the pages. Only organically gained backlinks, high quality content with reviewers wherever needed. It's not fighting spam instead it's their "crush the small guys so we can get more money from ads update"
