Some phishing campaigns are conducted with zero knowledge and thus are just spammed out with the hope of connecting to something the recipient does or a product the recipient uses. These are often very crude, and the example you posted is definitely a crude attempt. The sender did not even spoof the email address in the header information.
It's the intelligent, pinpointed, phishing campaigns that often cause the most damage. They often use stolen or cracked information to gain prior knowledge of the recipient, and thus intelligently target victims. Recently Microsoft had a large number of Outlook email headers along with subject lines stolen. Although the message bodies were not included in the Microsoft breach, the subject lines in themselves are enough to know what businesses a user is associated with in order to deploy phishing attempts that would be far more likely in succeeding.
The best policy to stay safe from phishing attempts is to never directly click on a link in emails, unless you are 100% confident in it. To be safe, it is recommended to not even click on links from entities you do business with, especially ones that are popular like PayPal, unless you initiated an action and are expecting the message. Be safe.
