Listen mate, look back at the entire Naruto series or any other anime for that instance. Whenever a character gets a new power they show one of the two things:-
 * Sigh

1. Character isn't able to use the power to its full potential due to lack of training and deals very little damage to the opponent

2.The character obtained the new powers in a time-skip or some battle and trains to master it

For intance, Naruto's rasengan, sage mode and even Tailed beast mode were products of training

And even if you say they are skilled shinobi, then please explain why it took madara almost all his life to master the rinnegan (after he obtained senju DNA) and took sasuke only few seconds to master it
