Are these skills for collecting from monsters or just from collection spots?

like lets say i got the collection skill over at wlo main site it saids this..

Collecting Skill
Everyone knows that even the most common items in WLO may have subtle and unique functions in game!

but it don't really explain what its for just like the other skills

what i wanna know if if i get all these life skills and lvl them up will i be getting more items from monsters and more rare drops?

because i don't wanna go get these on all my alts and then bam doesn't do jackshit if its only for collection spots like blue stones and white silvery then i'll only get it for newb collectors..
