Your wheels are indeed fine. 29'er MTB wheels that are tubeless ready.

To learn about wheels, you must understand how they're built and why. Your wheels have two unique interfaces to the bicycle: the hub axle, and the disc brake rotor. The hub axles are "through axle", which is defined by the axle diameter (yours, 15mm front, 12mm rear) and the fastener type. The disc rotor is generally defined by one dimension, the diameter of the flat disc. Internal to the wheel is the hub to rotor interface, of which there are a few types.

Other things to consider are the rim type, rim width, rim material, tube/tubeless, tire dimensions, tire type. These all matter if you have a particular application in mind.
