are sure about this?

I am new to the fighting game genre and I have seen some videos on the internet saying that "fighting games aren't hard, this belief is a stigma" and the people on these videos ALWAYS mention how much people are scared of combos.

I am pretty sure that the reason why everyone hates combos is due to this mechanic making hard to practice on them.

(also the people who are making these videos either are pros or have never seen a begginer trying to beat the practically impossible frustrating stressfull sorry poor excuse for a tutorial of skullgirls and dead or alive 6).
