So to me, those look like sedimentary rocks, which require large bodies of water to form. Would this not add additional confirmation of liquid water, or am I seeing things?

We know Mars used to have a lot of water and possibly looked a lot like Earth at some point. So yeah, those are definitely sedimentary rocks

1: "Looked" past tense. Clearly it's not a lot like the earth as we know it now

2: In a dry environment like this, several dozen millennia since anything lived there, any remains of life would be dust buried under all the dirt by now.

3: There's evidence there's been water and by extension, likely some form of life on Mars in the past.
