The given statement exists true. Ntering a system call concerns varying from kernel mode to user mode.

The transition from the user mode to kernel mode happens, when the application demands the service of the operating system or an interrupts or a system call happens. The mode bit exists set to 1 in the user mode. When a program requires any hardware resources, it must create a call to the kernel.
