No, it means that in both senate races in Georgia didn't produce a victor with >50% of the vote. What happens then is they take the top two candidates and hold a special "run-off" race on January 5th to decide who is the senator. Depending on how many seats the Democrats pick up either one or both of those seats would be needed to secure a majority in the senate- therefore the "decide who controls the senate". Be assured that if the republicans retain control- McConnel will still be SML- being the ruthless, soulless, shameless and devoid of compassion husk of a human that he is.
