lol, remember you are replying to a person who know probably the square root of nothing about fighting and has been blindly follow what the Russian told him except the call for people like him to fight for Russia (Which even people like him wouldn't answer, that's saying something)
What Ukraine did by pushing Russian out of Kherson is that it completely occupied the land West of Dnieper. Which mean they can use the river as a Natural Defence and free up all the troop along the entire frontline and only leave a few brigades to guard the entrance and approach. And this is what it looks like in Kherson Area BEFORE Russian line collapse

Each of those unit with an "X" on top of their box is a Brigade, there are 14 Brigades in the frontline itself, and 2 further back (1 in Mykolaiv and 1 in Vysokopillia) Another 2 in Krivyi Rih which is no longer the frontline.

Which mean Ukraine can move 4 Brigades into Kherson and Nova Kokhovka and redeploying the other 14 to somewhere else. If I have to guess, this is where they are going next, probably after winter

Notice the 2 dot and square unit? Those are Artillery Regiment, you don't put Artillery Unit behind a line if you are not thinking about breaking thru that line, and that 2 Artillery Unit was in Kherson just about a week ago.
If the Ukrainian successfully punch thru here and straight into Melitopol and Mariupol, then that's the ball game for Russia, there are no turning back and they can't possibly win this war. Even if they mobilise 10 million soldier, because that is the choke point of Russian logistic effort, once you cut it in half you can and will defeat both side in detail.
