Ecosystems are not static. There are also natural events that occur like earthquakes, meteor strikes, volcanos ... which upset the balance in some way allowing one species to dominate if they can adapt to the changing environment.
Well, i did not consider natural disasters because i don't think they have any role in humans becoming the dominant species, if you are talking about dinosaur extinction or previous extinction events ,it is never about only one species taking over,rather it is an entire class of organisms that start dominating the ecosystem they live in ,for example mammals got the chance to dominate after all giant reptiles became extinct but not ONE SPECIES ,it was the entire class of mammals but if you look at the current situation it is just human dominated.

You could compare it to using betting strategies in a casino. Each player representing a species. As they play at different tables (environment) with differing strategies one player may eventually dominate over another so the better strategy wins and is passed on to the children of the player...
Here the selection process would favor the one who came up with a better gaming strategy (the one with the better brain, the one who can remember better/can reason better/can adapt better to changing environments) as they played while the casinos change their gaming rules due to internal and external influences.
This is the way evolution works isn't it ? the same process has been happening ever since the start of evolution but never has one species taken over the entire ecosystem ,when ever a predator comes up with a new strategy the prey also comes up with a counter strategy ,if this was not the case then all prey items would have gone extinct when the first of the predators started evolving.
In the present human dominated ecosystem ,there are no such species with some special ability or technique to counter human intelligence.
If you observe other top predators in the natural world they all have some kind of limitations for example in Africa
(1) lions may be strong but they cannot chase down the fastest of
gazelles,they need to think twice before they attack a fully grown African elephant.hyenas give tough competition.Lion cubs can be killed by rival males which also leads to population control.
(2) cheetahs are the fastest land animals but they cannot take down large prey nor can they take down preys like gazalles if they don't time it right (cheetahs are faster but gazalles have more stamina) and they can have their hunt stolen away by larger predators.
(3) leopards don't stand a chance against lions or hyenas ,so they depend on tree climbing skills.
There can be many more examples but for human predators there seems to be no limitations on what or how much they kill or hunt.
