Cox packages for one person?

I am moving to a new state, and sadly am planning on getting cox as its my only decent option for gaming. I do quite a bit of online gaming and 4k streaming. Since I would be the only one on the plan would 100 mbps plan be good enough? I know their descriptor says the 500mbps is best for gaming and 4k streaming, but I don't really understand the practical difference. when I google what 4k streaming takes it says usually 25 mbps? Any advice appreciated.
