What is known—as an organization Twitter hasn’t always been forthright with the public regarding their practices (shadow banning, uneven application of rules regarding account suspensions). In some cases these may have been bad actors within the organization acting outside of the management’s knowledge, or even tuned algorithms towards certain topic preferences that have a more aggressive effect—but when discovered, the company does tends to deny and then quietly work to rectify the problem internally.

So did they lie about the bots? Who knows? Do they always tell the truth? Well, I think you could reasonably argue not quite.
