Like a number of other Nintendo Games (whether for the Wii or Switch), Super Mario Odyssey is compatible with all Amiibos. Random Amiibos that have nothing to do with the Mario Franchise will usually award players with bonus heart and Coins when scanned; however, certain Mario specific Amiibos will unlock certain bonuses and unlockables for players to obtain. Every single kind of Amiibo can be used with Uncle Amiibo (found only in certain Kingdoms) so it can aid you in finding certain Power Moons.
