Based on my research, I can verify this claim about Wilt Chamberlain.

Reasoning:

• Wilt Chamberlain reached the 15,000 career points milestone on January 24, 1964¹
• According to detailed statistical records, Chamberlain achieved this at the age of 27 years and 156 days (shown as "27-156" in age notation)¹
• Chamberlain is the fastest player to reach 15,000 points, accomplishing it in just 358 games¹
• This record places him among the youngest players to reach this milestone, with only LeBron James (25 years 79 days), Kevin Durant (26 years 78 days), and Luka Dončić (27 years 31 days) reaching it at younger ages²¹
• The date January 24, 1964 aligns with Chamberlain's 1963-64 NBA season when he was playing for the San Francisco Warriors at age 27¹³

Overall validity: 100%
