That is true, they are reliable. But we shouldn't go overboard with that. It used to their claim to fame was 'we launch on time reliably'. The 'we launch on time' is now no longer true, they had lots of issue with that recently. Arianespace had such issues too, Ariane 5 was actually grounded for most of last year. SpaceX is a far more reliable on time to launch by now. SpaceX has insurance cost as low or lower and they are certified for all military and NASA payloads. Including bieng certified for humans before Atlas 5 was. In terms of reliability the newest version of Falcon 9 that has the human rating is rapidly approaching 100 flights and never had a failure. Even if you account for all Falcon 9 launches, their reliability is still very good. Atlas 5 recently had a shutdown of the first stage engine and only because the 2nd stage was overpowered it was able to barley compensate. Had the payload been just a little heavier it would have been a launch failure. Arianespace also had reliability issues, they recently launched a payload somewhat in the wrong direction because they had the wrong software on the rocket.
