Serena Williams says "it takes time" to address gender pay equality in the sports world

Tennis superstar Serena Williams has long rallied for equality in gender pay in the sports world, but she told CBS News in an interview that addressing inequalities "takes time." 

"You just can't expect things to change overnight," the 23-time Grand Slam champion said. Williams, 40, pointed out that those attitudes toward it are changing, especially when it comes to equal pay. 

"I like that people are starting to recognize that women do deserve equal pay and they deserve the same that a male gets," she said.
