Interesting solution! But it was completely unnecessary to use any test. The numerator of each term is n^n, the product of n multiplications of n. The denominator is n!, the product of the first n natural numbers. The numerator is much bigger than the denominator for all n>1, so each fraction is more than 1 for all n>1, so not only does the series not converge, the sequence doesn't converge either.

You are absolutely correct! Just wanted to use the ratio test to prove this. Thanks for pointing this out. Will be extremely helpful for those who watch this vid.
