Is Standard Assets compatible on Android or IOS?

hi, i have recently started learning Unity, and trying to build my first 2D Platformer. for the beginning, i have decided to download and use the Standard Assets Pack from the Asset Store ( https://assetstore.unity.com/packages/essentials/asset-packs/standard-assets-for-unity-2017-3-32351#content ). from this pack i have used just the charachter prefab (CharacterRobotBoy.prefab).

however, my question is, if i build the game on Android or IOS, will this asset work? do i have to change anything in order for it to work? (of course, i started the project as a PC game).

also, i have considered using a touch joystick as the controller, since i have seen that there are some available on the Asset Store.

thank you!
