Most people over-estimate what DDoS protection provides. There are all sorts of tricky attacks. The APIs are now so complex there are lots of layers - load balancers, gateways, kubernetes, etc etc. The attackers can exploit any amount of them until they find it. It could be a bug e.g. integer overflow on a specific header or the lower TCP layers, etc. It can also be very tricky to detect and stop. You may imagine the attacks to be constant but they are not. They do enough to deny service but not enough to be detected. It makes it very hard to differentiate from real traffic.
