Advice Needed! Clutch master cylinder replacement? 68k miles

I mainly self diagnosed this as a clutch master cylinder issue and planning on dropping the car off today to get it taken care of. Chances of it being something else? Feel like this is low mileage for something like this to happen. Thanks in advance.
