You should really do your own research on this topic since it’s been discussed many of times using the search function would bring up the results your looking for. There are previous threads that leaves information, and ways to get started into learning modeling.
Consider starting with the common resource blender gurus beginner tutorial (donut & mug) as you would learn how things work such as the tools - interface, techniques, ect. Wanting to get into better learning blender to get 3D modeling animation and more; does take a lot of practice and patience as it isn’t something that will come overnight.
I would use the information and take notes to help you along the way, and search up the updated sources/tutorials. Late Response!
