Does the source of income matter when applying for a 90-day Non-O visa at the Thai embassy?

I will be using the Washington DC Thai embassy to apply for a 90-day Non-O visa soon after I retire at the end of May. One requirement is the following:

"Recent bank statement for the last three months showing the applicant's name and ending balance of no less than $30,000 or proof of monthly income of not less than $2,500/month) along with the current bank statement showing incoming income."

I will not have a $30k balance when I apply for the visa. And the monthly income shown in may bank account will be from my current employer (not SS and pension)

Will it matter where the income came from?
