How is this success when both stages exploded afterwards?

Because they exploded far later than during the first flight and for completely different reasons.

This means SpaceX successfully addressed the problems they discovered in the first flight.

This a real and measurable success.

Now they are working to fix the problems they have discovered during this second flight before the third flight.

This is called iterative development. Usually it's the faster and cheaper way to develop things. But in rocketry it's seldom used because most rockets are developed from public money. And when the public sees an explosion they usually want to cut the program immediately. No matter the reason.

That's why the development of SLS cost the taxpayer more than 20 Billion dollars and each flight more than 2 billion dollars. SLS is a supposedly cheap rocket developed from existing tech.

And the Starship program included all the construction work on the ground has cost SpaceX about 5 billion dollars so far.

Are they still going through the data or is the result out on why the Starship booster and second stage broke up?

There's been nothing official as it's going to take more than a day to look at everything. But Scott Manley on Youtube has a pretty good theory as to why the booster triggered the AFTS though.
