If you're still riding with a trainer then yes you're getting pretty low pay but that's what the training phase is like. If you weren't aware of this before then this will be an unfortunate realization at this point but the first year kind of sucks in terms of pay because until you've proven yourself a safe and competent driver you're a risk to any carrier so the ones willing to take a chance on you are not the ones paying the good wages. It's basically the 'paying your dues' phase of trucking. Get your CDL, get all you can out of training, get a year under your belt without any major damage or tickets, and you can take your pick of most of the jobs out there. Only an elite few may require more than a year - like the coveted Walmart fleet type jobs usually require two years experience and a clean driving record but even at the one year mark you can level up pretty easily at a majority of carriers. Also they'll all magically have your number as you approach that threshold so expect to start getting offers and requests to apply that simply didn't exist before you had the necessary experience. 

Also, don't fall into the trap of comparing company driver pay to owner/operator pay because they're two completely different scales. Company drivers aren't paying for the truck, the fuel, the insurance, the registration, the operating authority, the technology, the compliance, the cost of finding the loads, and of course the employment and pension costs. If you think you want all of that headache then by all means pursue owner/operator opportunities but be warned in advance that it's extremely difficult if you don't already have a financial cushion and the programs that carriers promote to own your own truck and be your own boss are extremely predatory and designed for you to fail because it's to their advantage.
