First off, the scenario OP outlines is not unique to TV, or Fla. for that matter, as many others have stated already. It also has little to do with funding or manpower, but more to do with availability of required resources to respond. It also might depend on the nature of the initial 911 call (heart attack, stroke, fall from ladder, non-responsive, etc.) and the protocol employed by that dispatch center.
It also happens that Emergency Services, particularly EMS, is primarily structured at the state and local level across the country, so you have plenty of variety in how things are not only done, but organized. A good example is the designation and location of a "Para-Medic" (versus an EMT) - In NJ, by statute, a Para-Medic can only be attached to a Hospital and dispatched with an ALS (Adv. Life Support) unit such as a Mobile ICU (Suburban or other big SUV). Fire Depts and Rescue Squads, paid or volunteer, can only be staffed by an EMT. Whereas, in Fla., many (maybe most) Fire Depts have Para-Medics on staff who are on nearly every engine/truck. Big difference on how quick that level of care might get to a call, based on who they arrive with.
Anyway, as many others have said.....wouldn't be too concerned about how many vehicles arrive, or who gets there first....so long as they get there quick!! Cheers!!
