Is an ecosystem random? What happens when one outside force is added to an ecosystem? There's plenty of examples around the globe of this.
Life doesn't 'find a way' and balance. The ecosystem is damaged, and often times destroyed by adding a single non-native species. That doesn't seem random does it?
Randomness should have error correction, as it's random. Doesn't seem to though.
Of course it does. "Ecosystem" and "species" and "native" are human terms referring to categories we invented to make sense of things. Life itself is one ongoing, unbroken, slow-burn chemical reaction at planetary scale. It's always in flux, it's always balanced in myriad ways on some timescales, unbalanced in others.
Even without getting reductive to this degree, there's hardly a case an ecosystem was destroyed. Adding non-native species ends up rebalancing things, sometimes transforming them into something dissimilar to what came before - but it's not like life disappears. The ecosystem is there, just different. Though it sure sucks to be one of the life forms depending on the "status quo".

Yes, it very much is random. If thermodynamics teaches us anything, it's that random looks quite organized if you zoom out enough and smooth over details.
