Now all in choir: liquids are incompressible!
Things aside, from an engineering perspective, liquids have a much larger resistance (bulk modulus) against compression than against shear. Thus, water is considered incompressible whereas steel isn’t, despite the bulk modulus of water is about 2 GPa and the one of steel is 160 GPa.
They were talking about the F1 teams chilling the fuel to fit some extra fuel inside the tank. As the thermal expansion of coefficient of fuel is about 1·10^-3 /K, they can fit another 1 % of fuel into the tank for every 10 K of extra chilling. However, this likely has its limits at low single digit percentage values, which is sufficient for some extra miles in F1 but not useful for dimensioning fuel tanks of the aircraft around that.

I’m fully with you here. The one or two percent thermal expansion/compression is way below the usual safety margin of a plane, anyway.
