If the answer to all of these are yes, then clicking is fine for you.
However, if you can't do any of those, then learning how to keybind everything may improve your performance in those areas.
Imo, in order of impact, learning how to keybind affects PvP the most, then Tanking, then damage, then healing the least. Compared to those other 3, healing is probably the only playstyle that actually can have downtime in the middle of a fight, meaning that saving yourself a fraction of a second with each action won't really add up much.
