Hi Emilia,
The mass of all the planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) put together is about 447 times the mass of the Earth. The mass of the Sun is about 333,000 times larger than the mass of the Earth, so the answer to your question is yes! The mass of the Sun is larger than the masses of all the planets in our solar system combined.
