matter in stellar nebula decides the life of star

less amount of hydrogen results in average star

more amount of hydrogen results in massive star

Edit: A very brief summary of the two main star life cycles:

Low mass stars (like our Sun): Main Sequence Star, Red Giant, White Dwarf.

High mass stars: Main Sequence Star, Red Giant, Supergiant, Supernova, then

either a neutron star or a black hole.

(Red dwarf stars should just go straight to the white dwarf stage after their time on the Main Sequence.)
