That is a page to Download Bitcoin Core wallet software. It's not a link to download Bitcoin blockchain data.

After you download the software, you will have two options to run your wallet, prune node or full node.
Both will download all blockchain data but prune node will delete data from past blocks that exceed the storage you set. Full node will store all blockchain data on your device.
