clicking in a HDD normally means its on its way out.
when its clicking does the PC fail to boot does the PC have any issues running?
check the health of the drive with HD tune but if I was you I wouldn't keep anything on the drive that you cannot afford to lose!
do you know if the clicking noise is coming from the HDD itself or something else in the PC?
Its saying both Performance and health is both 100% and estimated remaining lifetime is more than 1000 days. and the total start/stop count is 11. Is that good?
Your drive is currently fine, but it may be having the odd bit of difficulty when it tries to move the read head to a particular location. That could theoretically be caused by an underlying issue which gets worse. But there's no cause for serious alarm.
Still... if it were my drive I'd listen for increasingly frequent or loud clicks and check the SMART information every few months.
I will keep an eye on it.
