The world of Toy Story really is weird and we never find out how toys can be alive. The closest thing to an answer for why toys are alive is Forky in epilogue of Toy Story 4 being given a made up spork girlfrield and she asks "Why am I alive?" And Forky responds with a joke answer "I don't know."
We are supposed to simply see living objects as a fact of life in this universe because Forky is no toy.
