As others have said, Tyson can't pull the trigger anymore, we have witnessed that in the Jake Paul fight. Wherein we really fall for the hype that Mike Tyson can fight and deliver those knockout. While Floyd's style is not to get hit so he will run on this fight for sure. But there are fans that might watch the fight live and so bringing the money that is needed for this fight. And again, money grabbing, easy for both fighters, they are going to cash out their profit here.
For Mayweather it will be an easy money and easy win. Use hit and run tactics, gain points and win. For Tyson it will be hard money, because he would have to exhaust his body again by preparing for the fight and running to catch Floyd. It will be hardest cardio test for Tyson. Training at 60 yo aint no joke. Tyson aint no shaolin monk who has dedicated his entire life to training. He is enjoying his life, and now has to push himself to return to training.
But in the end, still good money for Iron Mike, even at 60 years old, he can gain $20 million as least (this is what he got from the Jake Paul fight, so I assume that he won't fight again for less than that). Although as you have said, he might have to take his body again and push it like he did in the Jake Paul fight so that there will still fans that is going to believed that he will have a good chance to win.
I'm not about if the odds are out, but it's obvious that the young Floyd Mayweather will be the favorite.
The next question should be, as there anyone here going to watch the fight live or buy in PPV?
