When Earth is tilted on its axis why does it orbit the sun ?

Here

Explanation:

Some assume our planet's changing distance from the sun causes the change in the seasons. That's logical, but not the case for Earth. Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees relative to our orbital plane, that is, the plane of Earth's orbit around the sun

Is that all the information privided? Im tring to figure it out but I feel like im missing something.
