Great question! No, they aren't. Your AGI includes ALL income you've received in a year, including investment and dividends, as well as some deductions and credits, as explained here https://turbotax.intuit.com/tax-tips/irs-tax-return/what-is-adjusted-gross-income-agi/L2C6rCEit:
"AGI calculation
The AGI calculation is relatively straightforward.
- It is equal to the total income you report that’s subject to income tax—such as earnings from your job, self-employment, alimony income and interest from a bank account—minus specific deductions, or “adjustments” that you’re eligible to take.
- Your AGI is calculated before you take exemptions and the standard or itemized deduction—which you report in later sections of the return."
while your EARNED is explained here (basically earned income only includes money you've worked for in some shape or form):
