You need supplements to grow healthily as a vegetarian. For example, it's difficult to get Omega 3, 6 and 9 from plants. You need supplements for that.
Also you've only been vegetarian a year. Being a vegetarian from birth to death without supplements would be much more difficult to do without major deficiencies.
Also vegetarians today have the option of buying food from all over the world, but that wasn't the case for the vast majority of human history.
