My sister doesn't see ads on Prime Video, but I do. My theory is that I order more stuff from Amazon than she does, so get enough value from the free shipping aspect that I'm not likely to cancel my Prime subscription, even though I've stopped watching Prime Video since the ads started. TV is just not good enough for me to watch ads, ever. I'll dust the furniture over watching ads!
