Incorrect.
If T3 is running and T1 puts in a run task event and T1 gets done then before rerunning T3, T3 will be serviced.
Or.
T1 will get more of the CPU time slice and the other 2 tasks will get less CPU time slice. Remember freeRTOS is also a state machine running a part of each task code as the switch is made from task to task.
Do not put code in the loop() when using freeRTOS. loop() is the only task that is guaranteed to not be ran per tasking iteration.
If task 1 is created first, task 1 will start to run first. If task 2 is created 2nd then task 2 will run 2nd. If task 3 is created 3rd it will run 3rd. As you may start to see each task did not start at the same time giving them slightly different task start times and end times. Which gives freeRTOS a way to break the tie.
