To understand this first you have to understand the structure of these big fours. These firms are structured as an interconnected network of member firms represented by an umbrella organization. For instance, the name Deloitte is actually brand representation of an umbrella organization called Deloitte Touche Tohmatsu ltd (dttl) which is a single point representation of member firms such as deloitte us, deloitte UK etc. Each of these member firms have their independent operation. They also report revenues separately. When you consider them individually they are not as big as fortune 500s so they are not there. The 34bn usd global revenue is just a number representing the collective revenue of all these member firms.
