This report includes complaints from the American public without splitting the data among organizations and individual users.
The complaints included the spectrum of cyber matters, like online fraud in its many forms including Intellectual Property Rights (IPR) matters, Computer Intrusions (Hacking), Economic Espionage (Theft of Trade Secrets), Online Extortion, International Money Laundering, Identity Theft, and a growing list of Internet-facilitated crimes. So, many of the complaints were not related to great losses.
The chances of great loss in an organization are significantly different compared to individual users. Anyway, we could use the data to calculate the upper limit:
Suppose that 2/3 of the US population (330 million) use computers with Windows.
According to the report, there were nearly 4 million complaints in the last 5 years.
4/(2/3*330) ~ 0.02 (2%)
Bearing in mind that many complaints were probably unrelated to great losses or were reported by organizations, the chances for individual victims can be much smaller (for example 0.2%). Among MT members the chances can be even smaller.
Edit.
Many incidents were reported by users of smartphones. Most of my friends and relatives use smartphones for managing e-mails and shopping.
