Nope Ticketmaster shares fees with its clients, this is from the Ticketmaster help...
-----
The standard tickets sold on Ticketmaster are owned by our clients (venues, sports teams or other event promoters) who determine the number of tickets to be sold and set the face value price.
...
Ticket fees (which can include a service fee, order processing fee and sometimes a delivery fee) are determined in collaboration with our clients. In exchange for the rights to sell their tickets, our clients typically share in a portion of the fees we collect.

Service Fee and Order Processing Fee
In almost all cases, Ticketmaster adds a service fee (also known as a convenience charge) to the face value price, or in the case of a resale ticket to the listing price, of each ticket. The service fee varies by event based on our agreement with each individual client.
In addition to the per ticket service fee, an order processing fee is typically charged. Unlike the service charge, which is added to each ticket, the processing fee is charged once for each order. The processing fee offsets the costs of ticket handling, shipping and support and as a result, the processing fee is generally not charged on in-person box office purchases. In some cases, Ticketmaster's order processing costs may be lower than the order processing fee. In those cases, Ticketmaster may earn a profit on the order processing fee.
In both cases, these fees are collected by Ticketmaster and typically shared with our clients.
