这段代码中有几个错误：

1. 在 simOneGame 函数中，缺少 return 语句，导致该函数不返回任何值。
2. 在 switchServing 函数中，只有当 i%5 == 0 且 i>0 时才会切换发球权，但是在第一局比赛开始前，i 的值为 1，没有进入切换发球权的逻辑。可以在 simOneGame 函数中先将 serving 设置为 "A"，然后在第一次循环前调用一次 switchServing 函数。
3. 在 Winner 函数中，如果比赛还没有结束，该函数不返回任何值。
4. 在 simOneChampion 函数中，调用 simOneChampion 函数时应该传入 probA 和 probB 两个参数，而不是只传入 probA。另外，应该将 simOneChampion 函数的调用放在一个 while 循环中，以便可以连续进行多局比赛。

下面是修改后的代码：
