What this video covers
The clip tells one story: a pipe burst on a Friday and nobody dealt with it until Monday.
That is roughly 48 hours of standing water, which is the window in which mold moves from possible to established. By the time work started, the colony was across the entire ground floor rather than confined to the room with the burst pipe.

The delay is what cost the money, not the pipe. Water damage is a clock, and the difference between acting the same day and acting after a weekend is the difference between drying a floor and rebuilding one.
