If I buy a token from exchange and hold it for 6 months then will it be considered as staking? I don't think that makes sense. So what I need to do to participate in staking?

What I understood is that I need to buy a package mentioned at the site for staking. Once I buy that package, I will be getting token from where ? I mean it will be from the tokens which are with team? And after 6 months that will be delivered to my exchange account?
