Yes. The larger or more massive a star is, the faster it has to "burn" hydrogen to stay in Hydrostatic equilibrium.

The largest stars, known as population III stars (Formed about 400 million years after the big bang) were massive and used up all of the available hydrogen in millions of years.

Our Sun, is not so massive, so will stay on the main sequence for about 10 billion years. Part of this, is not due to it's mass, but also because of the metallicity or the metals within it. This "slows" down the rate of nuclear fusion.
