I've done a lot of grinding and spent a bit of cash and trooper badges, and I'd say I've turned in around 250 rare souls total. I've drawn four 5* souls (1.6% chance or 1 in 62.5) and fifteen 4* draws (6% chance or 1 in 16.6). Based on what I've seen on the forums, there are many who have done worse than I have.
To the point of your original question, it's very possible to draw all 3* souls from a ten pack, and I have more than once.
