We don’t find as many human remains as dinosaur fossils because dinosaurs lived on the planet for millions of years, while humans have only been around for 200,000 years. Additionally, dinosaurs were not just one species but had hundreds of different types, while homo sapiens is only one species. Furthermore, some species of dinosaurs were exceptionally huge, making their bones easy to fossilize, while humans have relatively small skeletons, which are not as favorable to fossilization.
