Maybe from an AI perspective, it's impressive that the bots almost managed to learn the rules of the (still drastically simplified subset) game. From a game skill point of view, it's a joke; it's incredibly obvious that the bots were only able to prolong the game due to consistently better than human mechanical skill.
Of the list of skills you mentioned that the bots "learned", on the main stage, the draft was provided by humans, and from a significantly limited set, the bots never pressured highground, checked for Roshan when it was impossible for it to be up, had nonsensical placement of vision (placed vision where vision already existed), continuously invested in anti-invisibility consumables even when the opposition team had no invisibility.
If the mechanical skills were toned down to human levels, I don't think the latest iteration of the bot on the latest ruleset can even compete with the average human player, much less the pros.
