I don't believe that. When it were true, Cairo would be right on the equator (shown in video) and the same applies to New Caledonia. Australia would be just still completely in the southern hemisphere with the northern tip of Qld hitting the equator and Europe in the northern tropic zone and Antarctica not within the arctic circles at all.
However there are no signs of any ancient tropical climate in 10500 BC in Europe and no vegetation or larger mammals in Antarctica as well.
The video also talks about 'celestial pole shift', but that is indeed true, we call this precession. But that has no influence on the location of the terrestal poles or equator or climate.
