That's because the Olympic class liners were built with a power plant optimised for fuel efficiency, not speed.
They had two reciprocating triple expansion engines and a low pressure turbine driven by the exhaust steam from the reciprocating engines' low pressure cylinders.
Fully turbine driven liners of the same era would easily clock service speeds well beyond 25 knots, at the expense of burning way more coal.
I too subscribe to Oceanliner Designs on YT.
