Does everyone gets their happy endings?

"Endings" is rather a vague term. For our purposes, we shall treat the term "happy endings" as an ongoing event rather than a tertiary event.

Any event can have a happy ending if there is a fortuitous outcome. This does not mean that the event turns out like the person expects. Most often there are unexpected outcomes, but in the main, an outcome that does not harm the person is a "happy ending".

On the other hand, what often is seen as a "happy ending" is not. The person involved might get the wished for outcome, but it might not be the "ending" that was best for the person.

Serendipity often plays a part in the idea of "happy ending." And unexpected outcome of an event can often look like a sheer disaster for the person. But in the end, a person becomes stronger, wiser, or more experienced with each event.

Therefore it is this writer's experience that, even though it doesn't initially look like it, all people get their "happy ending".
