I would echo that.... ATC is a fantastic career, but I wouldn't use it as a fall back if flying is what you aspire to. . Depending on which way you go it can cost around £50k to take the courses (Aerodrome and Approach Surveillance). If you manage to pass that, and have a job. You have to go through a period of 'On the job training' (OJT). For this you have to complete a Unit training plan which comprises of tests and practical exams for each discipline (Aerodrome and APS).
The time will vary from unit to unit depending on the complexity, staffing, and your ability.
Once, and if you have satisfied the requirements of the Unit training plan. The unit will put you forward for initial validation (If you do not pass the UTP, then you and the company will say goodbye).
The relevant Civil Aviation Authority will arrive to examine you with a representative amount of traffic.
If you are satisfactory and following a verbal exam on procedures, you will be granted an Air traffic controllers licence.
This is just a snap shot and from the UK.
To find out more you need to Google the ATC colleges in the country you are looking at.
You can get employed to train. NATS in uk, Airservices in Aus etc.
I could almost guarantee that if you told a selection board that you aspired to be a pilot but didn't make it and thought ATC would be an alternative (I know not in those words). You would not get too far.
Good luck Sarahvd88 on whatever you decide.
