Is Senna currently self-sufficient?

So, I'm currently a neeko main but want to expand my champion pool, I don't like champions that rely too much on teammates, have been recommended Pyke but I feel like way too squishy during TFs.

So I found Senna being referred as a "carry support" and for the few games I've played, I can say I really love her play style and champion concept, however looking here in reddit seems like she's not great at dealing damage anymore?

I'm not really looking for a "1v9 carry support" champion but wanna know how impactful Senna can be during games
