Sorry to be a pendant Leeroy, but that's not they're saying. You need to look at how many points 6th place got in those years and then add a point as they would have hypothetically been enough to secure 5th:
22-23: Brighton 6th (62 points) - therefore 63 needed (or better goal difference)
21-22: Man United 6th (58 points) - therefore 59 needed (or better goal difference)
20-21: West Ham 6th (65 points) - therefore 66 needed (or better goal difference)
19-20: Spurs 6th (59 points) - therefore 60 needed (or better goal difference)
and for good measure
18-19: Man United 6th (66 points) - therefore 67 needed (or better goal difference)
Regardless, it's many cases as you say it's more than 60. Usually mid-sixties. Maybe 2 more wins.
Still can't be dropping points like we did yesterday!
PS. Hopefully it's not like 2016-17 when you needed 70 points to beat Man U in 6th place and finish 5th
