Is it intended for a jungle to gank 3 times before level 6?

Is jungle camp meta intended? If not why do they get to camp me, come ahead in gold and exp and not have to actually jungle at all? Lets just clear out the jungle except for red and blue buff since i guess it's not very relevant now

At this point it really feels like the only purpose to the jungler is to gank at level 3 and then level 5 and then smite the baron and you win
