SpaceX has been launching the Falcon 9 for the past 6 years straight with only two launch failures and one partial failure out of 65 flights. Their older Falcon 1 didn't do great, only last flight survived out of five tries. However, SpaceX has had near consecutive launch success for the past 10 years. They threw themselves into the deep end with space. They do things the cheap and quick way and hope that it works. When it fails, they can quickly reconfigure and try again, their investment is low. This model helps you get really far really quick, so much so that they are now competing with ULA. ULA's tech has heritage all the way back to the Convair days when slapping a satellite onto an ICBM was a new idea. All of those small companies like Rocket Lab are just starting their success but this is literally where SpaceX was 10 years prior, launching small stuff with mixed results. If SpaceX can get off the ground with 20% success rate of their first design, I doubt Rocket Lab will have trouble with 80%.
