The tank will always be in the process of cycling if there is presence of ammonia. Even just 0.1ppm of it.
As we do not recommend 100% water change, partial water change will always leave some ammonia in the tank after the water change. Not to mention the fish are still producing ammonia between water changes, which means there is always ammonia in the water. Only a fully cycled tank can convert ammonia as quick as the fish produce it.
Water change will only slow down the cycling process, but it won't stall it. The more urgent problem here is the fish will definitely die in a small bowl without immediate partial water change on daily basis. You may get away with fish dying if it is a large tank, but it is not the case here as ammonia concentration can raise very quickly in such small amount of water.
