Is this game beginner friendly and active in lower ranks?

I wanted to switch from GGST to this game.It was my first fighting game so i had pretty rough time trying to learn fundamentals while also nonstop pracising inputs.I also picked a very hard character since he was the only one that interested me...Ive heard this game had something called "easy inputs",does that mean 1 button=special attack?And on the top of that characters looks top tier
