I heard it's when stars much bigger than ours run out of fuel and collapse upon themselves, but then I heard it's when a supernova occurs and it implodes? Can someone please give me a straight forward answer? Thank you

Hello, Like you said Black holes come from stars, as you know the fuel you are referring to are the reactions that happen in the core of the star like it goes in our sun (our sun is also a star) when there is no more resources for this reactions to continue. When a star collapses it explodes shooting some parts of the star into space, during this event in the very core of the star a black holes is formed. Do notice this only happens with big stars. So its not possible for our sun to have this particular event because it hasn't got enough mass.
I hope this has helped you.

Hi:
To understand how a black hole forms you must understand when a star like our Sun when was formed. It in a Battle between gravity that wants to crush it into oblivion and the nuclear Fusion that keep gravity from doing that. the star will shine on as long as the Nuclear fuel holds out ( mainly hydrogen ) Stars like our Sun are Low mass stars and will end their lives forming a white dwarf star ( basically it the core of the sun slowly cooling down to one very huge Diamond due to the electrical forces being able to stop gravity from crushing it further . however stars that have 5 time more mass than our sun will die in a Supernova and the electrical forces are Not enough to stop the collapse of it and the Protons and the electrons of the star combine to form a Neutron star . this is a star so dense and has so much weight that 1 Cubic inch of it would weigh several billion tons and all the people of earth combining there strength could not even lift it . It Just One big Neutron.
Now if a star Has 20 + times the mass of the star it when burn it fuel out. It dies in a Supernova Explosion and there is no know force that can Prevent gravity from crushing it into oblivion . all the mass of the star core is compress to a single infinitesimally point in space before this happens . it send out Neutrinos and two Gamma ray burst out it. during this collapse the space around it is bent torward and around the Black hole which cause the time around it to be distored so time is drifferent
and a black hole is born for more info check those websites:

You just described the same thing. A star much bigger then ours is most likely a super Nova and when a supernova runs out of fuel it collapses in on it's self and either A) explodes outwards causing a tear in space a.k.a black hole or B) becomes super dense and continues a few more million years as a white dwarf.

Anything that causes a lot of mass to occupy a tiny amount of space can cause a black hole. There is no one specific way.
