To get a DV visa, you need to provide evidence that you will not become a financial burden for the US government. This evidence can consist of many factors such as: bank statements, pay stubs, employment letter, W2s, tax records, affidavit of support I-134, or a combination of these factors. They also take into account if you are a student on the way to getting an advanced degree to asses if you will be able to find a job.

However, they never asked for 5-6 times the poverty guidelines. For an I-134 I think 100% of poverty guidelines are required. For I-864, 125% is required.
Moreover, I-134 can be signed even by somebody who is not a US citizen or LPR.
