buy means you make an offer to buy a specific item for a specific price and wait for a seller to accept this offer.
buy immediately means you accept a sell offer among all items offered by various sellers for their asking price.

But you'll need to make a store purchase or add funds to your account plus, wait the 15 days since you enabled Steam Guard to even use the Market.
