Is it cringe to use 3d models for references?

so, I have kind of a moral struggle. I had been drawing for approximately 1 year, and Im still bad at it, so a while ago I decided to use some 3d models(especially app Poselt) as reference, and it turns out pretty good (as can be seen in slide 2), but Im afraid that this is not a good way to do art, and that it will also ruin my learning curve, so... Is it ok to use them? Do you have any tips to replace it or something else?
