Is there a difference between threatening suicide when you don't plan to follow through, and actually committing suicide?

Because my understanding is "threatening suicide" as a means of control is done when the person expressing the suicidal thoughts isn't actually suicidal.

But someone ACTUALLY killing themselves, that's not about control. That's about their own desperation.

It feels wrong to label someone's last desperate act of despair as a form of "manipulation", as if it was being done "all for attention" when he actually acted on the suicidal impulse and actually killed himself...

IDK. I have had someone threaten suicide at me (my mother, who said if I supported gay marriage it made her suicidal). I've also had loved ones express suicidal thoughts to me, and even attempt suicide, but NOT as a form of control. Where they told me how they felt genuinely because they wanted me to help them. The two are very different.
