The required experience on a job listing should be used as a guideline. Usually, requirements describe what the company wants in the perfect candidate.
Not all of the listed requirements are usually required. Employers know that it is unlikely they will find someone who will fill all the boxes.
You are therefore encouraged to apply for jobs even if you have just some of the requirements, and not all. This is especially true for positions that you feel you can do well in.
Even if you meet 7 out of 10 requirements, perhaps every other candidate will meet 6.
