That's 100% false.MbL Yo went 6/0 for MbL in the last year.
They are tied at 4-4 and almost every set they played went the distance. The two latest wins of MbL against Yo before yesterday were a BO1 and a BO3 - all on Arabia on smaller events -, his only win vs Yo in a BO5 before was back in August 2018 in the final of Legacy of the Huns.
They are very, very close, especially on Arabia, but Yo's tournament results are clearly quite a bit ahead of MbL's.
