Apple did reportedly reserve all the initial 5nm capacity but I don't think we can say that's the reason AMD are still on 7nm. The early state of any node better lends itself to lower power, small SoCs. AMD may have been offered some capacity and turned it down because they prefer a more mature process for their larger chips with high-speed IO. Given the shortages now maybe with hindsight they regret that - who knows.
