I guess kind of? It depends on the game really. Some games give you extra items, like money, health, and equipment, though you don't have to continuously pay for them. You can re-use it as many times as you want, and it is something usually abundantly available in the game, so it's kinda yes-and-no.
Amiibo do other things, like an AI partner, save data, unlock characters, and add lil other modes. So they do all sorts of things. The nice thing is that as long as one person has that amiibo, everyone can benefit from it. So it makes it a lot easier to get certain things you want. And plus, you get a nice figurine, so that is neat.
Dance my pretties!
