We have come to expect phishing emails that pretend to be your bank or offer you amazing deals with Amazon.
So when a misspelled email asks for your banking password, or a link points you to "amason.com", or you get asked to install an attachment to reinstate your account, you know to not do that. You've read about phishing emails, you know better.

With many people using the same passwords for multiple sites, getting just one password from one person can unlock dozens of sites.
