yes, that's correct.
But keep in mind that Traffic, Burstable and Unmettered series just make sense when you have more than 1 server.
The standard series give you 100Mbps for Kimsufi servers. That's the bandwidth for all your servers together or infrastructure. So, if you just have 1 server, this is the best option.
If you have more than 1 server, the bandwidth will be divided as follows in the next link:

In that case is when other series would start making sense as they could ensure you'll get a certain guaranteed bandwidth per server.
Hope that's clear things up for you
