Yes, but few grew up rich and pampered to the extent Vlad was. Vlad never had to work, as his forebears did, unless playing baseball is work. His gut is a product of genes ill equipped for a leisurely lifestyle and grandma's cooking.
"Vladimir Guerrero Sr. grew up not far from his current palatial digs in a tiny house made of mud brick and originally roofed with palm leaves."
Take a kid who's forebears all grew up poor, having to work hard, and with little food, and give that kid a pampered lifestyle with plenty of food, the end result is predictable.
