Many people believe that certain tools can design for them and they don't need a help of a professional designer.
In fact, any design is based on 5 basic elements: text, colors, shapes, images, and space.
Those fundamental elements are the core of any design, whether it’s a website, banner, or business card.
Design software
Most common design tools, such as Photoshop, Figma, Sketch, Adobe XD are only the tools that help to use those five core design components and mix them around to create a good design. But they don't necessarily design things themselves. It is similar to expect a pencil and paper to draw a professional painting without an artist.
Outcomes
It is why you need a specialist in design even if you have downloaded those design programs. The only difference between design software is its usability that they provide, plus additional benefits, but that's it.
A good design is the use of the right combination of those core design elements (text, colors, shapes, images, space).
Keep it in mind, programs and tools don't design for you, designers do.
