The whole internet is bots on top of bots. If the traffic experts at Cloudflare with their Analytics product, with 'exclude bots' enabled still report 95% traffic that is clearly coming from residential proxies, how reliable are Google Analytics and Google Adwords statistics?
I wouldn't be surprised if advertisers paid 3 times as much as they need to.
And there's no incentive for Google to put more effort into blocking as long as advertisers are willing to pay up.
