No, if you start from scratch buying the battle pass definitely is not enough. As mentioned in the starting post, you can only get a total of 7 Emotes, 2 Footsteps, 2 Animations, 19 Skins with the battle pass. You would have to spend some more money on the mobile version and even then it isn't enough. Although I haven't checked the mobile store today how many items you can get there at the moment.
