Floyd Mayweather says he doesn't care that 50 Cent and Manny Pacquaio call him "uneducated" -- because he says if it's true ... "it makes my story that much more interesting."

Mayweather was talking with Brian Shapiro from The Vegas Take on Fox Sports 670 -- when he said personal attacks are just part of the job.

"When you get to this level, people are gonna take shots at you in every way possible."

Mayweather also said he's not bothered by all of 50 Cent's social media smacktalk -- saying, "My beef is with boxers. I stay in my lane."
