I have been attempting to create a timer for my game and I heard about QueryPerformanceCounter and QueryPerformanceFrequency. Could someone please explain how these can be used to calculate time/fps/ticks in a game loop?.

Microsoft support has a Knowledge Base article specifically about this:
How To Use QueryPerformanceCounter to Time Code
Basically you use
QueryPerformanceCounterto get a high resolution timer value before and after the event you want to time.Then use
QueryPerformanceFrequencyto get the number of ticks per second. Divide the time difference by this value to convert the value to seconds.
