There are huge differences in quality concerning the density of the material and, for example, whether the carpet can be laid on a concrete staircase. If so, it should be possible to bend it in at least one direction, and the backing should not be visible.

You can't get this kind of thing cheap. Carpeting on stairs is by far the most expensive flooring in the whole house.

If the carpet is only laid on a flat surface, it does not necessarily have to be as dense and hard-wearing as the stairs, but if you want to enjoy it for several years, it is better not to save money.
