The same is true in Pokemon Sun and Pokemon Moon (and their enhanced rereleases, Pokemon Ultra Sun and Pokemon Ultra Moon) - you won't be able to get yourself a lucky egg until much later in the game, but it'll still prove useful if you're training up teams for multiplayer battling or post-game content such as the battle tree, a location where you don't earn exp so your level going in is all the more important.
