No they didn't, you've already identified that the tower that was hit first fell later so there must have been some diferent mechanics at work in some respect at least.
However, two essentially identical structures were damaged in very similar ways so a very similar failure mode could well be expected although it would be by no means certain.
As for probability well it was certainly more than zero as that means it cannot happen and, it clearly did happen. It would have been difficult to calculate because of the very limited historical data available but a working estimate could have been made and probably was to a limited degree, (hence the claims that they were designed to sustain "multiple 707 impacts"). In the example of the marbles the probability certainly is zero, not because it has never happened before but because there are no red marbles in the bowl so the condition where a red marble can be selected cannot occur.

Especially when WTC7 fell due to only 2 floors being ravaged by fire.

In such a supposedly "random" and unexpected event?
If the planes hit the 2 towers at differing angles,heights and velocities, why is the speed and nature of both towers collapse identical?
If the steel (as the BBC say) was weakened to the point of collapse by the heat, why did the 2nd tower to be hit, fall first?
Leaving aside any "temperature required" issues.

The towers falls were not identical. The south tower tilted slightly before the global collapse. The north tower did not.

The original question was 'what are the chances'. I interpret that to mean 'what is the probability...'. That being the case, the answer is 0. Since there had never been a collapse of this kind of structure ever before there would be no precedent against which to calculate the probability. Therefore the answer is 0.
An example: You have a bowl with a random number of black and white marbles in it. You select single marbles and note their color returning them to the bowl. After some number of selections you can calculate the probability of choosing a black or white marble (based upon your earlier selections). If asked, 'what is the probability of selecting a red marble your answer would be: 0. Never happened before so has 0 probability.

Given that September 11th was not a windy day, and that there were nt throngs of people in the upper floors, the critical load ratio was probably well over 10, meaning that more than nine-tenths of the columns at the same level would have to fail before the weight of the top could have overcome the support capacity of the remaining columns.

On February 13, 1965, real estate baron Lawrence Wein called reporters to his office to charge that the design of the Twin Towers was structurally unsound.

WTC7 collapsing.
Not to mention the mysteries still surrounding the Pentagon,
and whether or not the other plane was shot down in Pennsylvania or crashed due to heroic passengers.
Not to mention the coincidental NORAD exercises going on that day.
I wonder what the probabilities would be for all of the events combined.
Would be a mind boggling number, to say the least.
2 cents.
