Schools get funding based on a 'per child' basis - doesn't matter to the school whether the kid is illegal or not because each one is worth additional money.
Emergency rooms have to treat everyone whether they can pay or not and the cost is written off or charged to the rest of us through higher medical costs - so called 'free clinics' are privately funded, usually by donations or through Trust Funds.
Illegals seldom try to get government programs like 'food stamps' or educational loans because it opens them up to government scrutiny - most illegals try to stay under the 'radar'.
