Does buying all flats give land rights?

In high rise apartments, you have a tiny share of land called UDS as there are 100+ flats constructed on a small piece of land, whereas there are options of buying flats in G+2 in gurgaon. For example, societies like Malibu Town, emaar emerald hills sec65, blossoms, m2k whitehouse, etc. If I buy a ground floor apartment in G+2 and over a lifetime, buy other 2 apartments of first and second floor as well exactly on same plot i.e. on top of my ground floor apartment. Can i assume that i have received complete land rights? As I don't have capital and risk apetite/guts to buy a big 267 yard plot at a time but anticipating that i will have capital in next few years by selling other assets in other towns.
