What would these laws mean?

I copied these laws from the Nevada government. Does this mean I can work at age 14? I’m confused because it says nobody under 14 but then it says stuff about being 16. Help!

NRS 609.240 Maximum hours of employment of child under 16 years of age.

  1.  No child under the age of 16 years may be employed, permitted or suffered to work at any gainful occupation, other than domestic service, employment as a performer in the production of a motion picture or work on a farm, more than 48 hours in any 1 week, or more than 8 hours in any 1 day.

  2.  The presence of a child in any establishment during working hours is prima facie evidence of employment of the child therein.
