they have jaws and can bite. Also, they have a stinger, but I'm not sure if they die after stinging.
That is correct, they have a painful poisonous sting, and they do not die after stinging. The honeybee is unusual in that way; hardly any other insects die after stinging.
A little of both, the pain one feels is from the sting of the ant, like most stinging ants harvesters grab on with their mandibles before stinging.
they dont sting, they bite.
They can sting and bite
Sting
Some ants sting, but there are thousands of species that do and don't sting. Most "stinging" ants actually bite, although some ants have a stinger as well. Nearly all red ants sting (or bite). Some other black ants sting, but it is hard for the average person to tell between them.
All ants bite or nip if you like with their mandibles which are capable of delivering a poison. Personal experiences: Yes, it is true. My wife was bitten by a common black ant and I white pimple appeared with some redness. I never thought that they would bite because I have neven been bitten by a common black ant. A red ant, absolutely. The Texas red ant which is huge, has bitten me and it really did sting and hurt. My ankle swelled up. Over a few days, the swelling disappeared and all was well.
Ants sting rather than bite. The common black garden ant in the UK doesn't sting people, but they do have ants that will. These include wood ants and flying ants. Another ant in Britain that stings people is the red ant.
Methanoic acid
The pain is due to the formic acid in the ant's bite.
Yes, the ones we have in Hawaii do bite. Their bites sting and then they leave welts for a few days.

Ants do not urinate on people when they bite them because they typically do not urinate at all. They can however secrete a poison when they bite which can be painful.
When some ants sting the acid they use is called formic acid.
