The camera is probably not the main problem. From the answers, the biggest issues are lighting and lack of post-processing.

Your light appears too direct and too close to the lens axis, similar to built-in flash lighting. That produces flat, harsh results with little shape or depth. For product photography, use off-camera light from an angle, soften it with diffusion or a softbox, and experiment with placement. A common starting point is one stronger light from above/one side, then a weaker fill light from the opposite side. Natural window light can also work well if it’s even and soft.

Because the subject does not move, put the camera on a tripod and use longer exposures instead of harsh direct light.

Also, professional-looking product images almost always need post-processing. Adjust white balance, brightness, contrast, black/white points, color, and sharpening. Even a good photo straight from the camera often looks dull until it is edited.

In short: improve the lighting setup, avoid on-camera/built-in flash, use a tripod, and plan to edit the image afterward.
