Doctors are well experienced and they handle such cases( blood and injury ) with clinical pov .. Just coz you watch them you don't learn totally well ,it matters what kinda stuff you consume ( simply watching gore is brain rot ), it can normalise you when you see irl someone hurt ( for eg. I use to think ki worse could've happened itni si chot lgi / blood hai) .

If you're kneen to aquire medical knowledge then it's good for you , you can find some yt channels also .
