Proof or refute $n^n = \Omega(n!)$ with the help of Stirling's approximation

Question

I'm trying to proof/refute the following equation:

$$n^n = \Omega(n!)$$

Generally I would try to use Convergence Criteria and or l'Hôpital's rule to solve such a problem.

$$\lim_{n\to \inf}{{f(n)}\over{g(n)}} = K$$

However, in this case $n!$ is somewhat of a party-stopper. I found Stirling's approximation which states that:

$$n! \approx \left(\frac{n}{e}\right)^n\sqrt{2πn} $$

My idea was therefore:

$${n^n}\over{(\frac{n}{e})^n\sqrt{2πn}}$$ $${n^n}\over{\frac{n^n}{e^n}\sqrt{2πn}}$$ $${e^n}\over{\sqrt{2πn}}$$ $$\lim_{x\to \infty}{{e^2n}\over{2πn}} = \infty$$

$$ 0 < K \leq \infty $$

therefore the original equation is true.

Is that approach "ok", did I understand Stirling's approximation correctly?
