I don't see the contradiction to what I said or what the prior commenter said.
CPU requests still protect you from something using all the resources, because the weights correspond to your number vs all the other pods on that node, and the scheduler will not schedule pods so they exceed the total available resources.
So more accurately, requests prevent exceeding limits under contestion, and limits always do.
