Short answer : No.

Long answer : Limited samples does not justify your conclusion.

 1. Phish campaign are never free, phisher need to make sure there is enough target fall into victim. 
 2. Regionalised phishing campaign increase success rates. A phisher will make use of online advertiser regionalised tracking features. 
 4. Phisher also run their own statistic on the phishing campaign, to tune the layout, wording, etc.

For example : 
So if you go to popular regional website, when you click on the phishing advertising campaign adverts(which can be anything that you deem interested), it will send all the regional information, including all the advertiser tracking information to the phisher. Then the phisher just show you correspondence contents according to the region. The infamous ransomware are indeed using this tactics, e.g. show crafted Italian page when it know you are a Italian user, show a German page to German user. 

That's why a tracker blocker/ads blocker will mitigate a lots of malware campaign, because it reduce the entropy of tracking information relay to the phisher through online advertiser.
