Why is LIVE TV delayed 45 seconds?

I know this problem is heavily complained about and have no real answer, but I wanted to make sure my issue was recorded when there is hopefully some sort of lawsuit.

Why is the live broadcast on my cable box 45 seconds behind the Xfinity Stream app? And 1 minute behind ESPN live score updates? Friends watching games via streaming services text me game updates before I see the plays occur on my cable box.

• Xfinity is literally running a commercial during every football game this year about how their internet is so good that their streams aren't delayed 
• This occurs on almost every channel. Some are more delayed than others. Local channels are affected the most. Fox right now is 45 seconds behind the Stream app
• Xfinity Box: XG1v4-A
• For comparison, I am streaming the game at the same time on my Apple TV 4k via Xfinity Stream. I am 45 seconds behind.
• I have changed out the HDMI cables, both HDMI 2.1 and HDMI 2.0 versions. I have tried different HDMI inputs on my TV
• I have done multiple system refreshes
• This has been happening for 2-3 years w/ 2 separate Xfinity boxes. It has recently gotten worse though. 

Is there anything I can do locally until Xfinity maybe improves their connection between the channels and their customers?
