If the Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, total solar eclipses would occur every month… however, it isn’t, so we don’t.
Despite the belief that solar eclipses are more rare than lunar eclipses, it’s not true: somewhere on Earth approximately two of each are seen each year – the range of sight for a solar eclipse is so narrow however, that most people don’t see them.
