I'm really new to AWS and quite confused on the purpose of Glacier vault, when I can archive my objects thru S3 via lifecycle rule? so do I have to first setup Glacier Vault for me to archive my objects?

Once upon a time, there was a service called Amazon Glacier. It was very low-cost, but it was very painful to use. Every request (even listing the contents of a vault) took a long time (eg make a request, come back an hour later to get the result).
Then, the clever people in Amazon S3 realized that they could provide a more friendly interface to Glacier. By simpler changing the storage class of objects in S3 to Glacier, they would move the files to their own Glacier vault and save you all the hassle.
Then, the S3 team introduced Glacier Deep Archive, which is only available via Amazon S3 and is even lower cost than Glacier itself!
The children rejoiced and all cried out in unison... "We will now only use Glacier via S3. We will never go direct to Glacier again!"

No you don't have to. You use Glacier Vaults if you want to use extra features that S3 Glacier service provides, such as Vault Lock Policies and/or Vault Access Policies.
For using just the Glacier storage, you can use Amazon S3 service and lifecycle rules.
