Only the most braindead of gamers has a chance of bouncing off a single Souls fight more than maybe a dozen times. Two dozen if you're especially thickheaded.
The thing about Soulslikes - and Fromsoft games in particular - is that they teach you new things primarily by killing you with them. Once you know whatever the thing is that this encounter is trying to teach you, you can blow through the entire thing at level 1 and people do it all the time. And I do mean "people" and not just professional streamers. SL1 is a popular challenge run for souls fans, specifically because once you know all the rules of the game it becomes very easy.
But there is no easing-in to learning new things in Dark Souls. You will get flattened into paste by some bullshit without warning, and it is up to the player to figure out a) why they died, and b) how to prevent that. Throwing yourself at the same brick wall 200 times with no change in strategy is a losing prospect no matter what game you're playing, souls or otherwise.
The essence of "gitting gud" is literally just stopping for 10 seconds to think about why you failed last time. If you're capable of that - and 99% of gamers definitely are, it's a core component of game design - you're capable of not only completing but excelling in Soulslikes.
People have been jerking off how difficult Souls games are for a decade and a half now and it's never been true. Souls games are just rhythm games that don't give you the rhythm onscreen. Find that rhythm (through observing patterns, and especially through listening to the boss fight music) and you'll first-clear every single fight.
