No wonder you're confused. The Singapore Ministry of Foreign Affairs only references Indian nationals being eligible for 96-hour Visa Free Transit Facilities (VFTF). In addition, the Consular Services in Beijing make no mention of it.
However, the Singapore Airlines visa and immigation requirements page has a Get personalised requirements link, taking you to IATA Travel Centre and the Timatic tool used by airlines to check passenger visa, passport, and health requirements. Using the parameters you shared, my search on Timatic indicated that you would not need a visa.
With the details you shared, I queried the Singapore Consulate in New York, firstname.lastname@example.org, which responded:
The 96-hour visa free transit facility is subject to several specific conditions and entry requirements. Your airline must also confirm that it is willing to board you under this facility without a Singapore visa. In addition, final entry into Singapore is at the discretion of the duty officer at the Immigration checkpoint at Changi Airport. Should you wish to check on your eligibility for the 96-hour visa free transit facility, please email your complete detailed itinerary to ICA at email@example.com for their assessment. The Singapore Immigration and Checkpoints Authority (ICA) would encourage you to apply for a visitor visa to avoid any unnecessary problems upon arrival.
You can visit our website at www.mfa.gov.sg/newyork-consul for information on how to apply for a visitor's visa to Singapore. The documents required are under Visa Information>Countries Requiring Visas to Enter Singapore>Assessment Level 1 Countries or this link. Please note that our processing time is three to five business days plus any mailing time from our receipt of a complete application.
Sincerely, Consulate of Singapore
