Yes, their cost per kg for launching is higher than SpaceX.
But it's their first launch from a new company. It's expected to cost some more to start with. I presume the price is going to come down quite significantly over the next few years.
RocketLab will never be as cheap, but the business plan isn't to compete on price. The business model is that with smaller rockets you can have much higher launch cadence, much higher throughput (i.e. you can book a launch and have it launched a week later), and more customisable orbits (since it's cheaper to book out an entire launch).
