Why do you think that?
It's hard for me to imagine your situation since I already sunk around 2k hours into the series and my first steps with it back in 2012/13 are fuzzy in my memory but I'll do my best:
1. You can brute force basically everything. "Gittung gud"- as the meme goes - sure helps but since it's still an RPG you can always just grind XP and upgrade your gear to make things easier.
2. Your first blind playthrough will probably be crushing since KNOWLEDGE is a huge factor. Knowing enemy patterns, traps and even just routes throughout the world makes the biggest difference imo. My first playthrough, blind, took me about 70 hours (still have that char save on my ps3) and my second already reached the final boss in 20.
4. Looking up a guide about character building is no shame. The game has some worthless stats that you can invest XP in and some weapons are just plain bad and have objectively better variants which is impossible to know as a noob.
5. Loadout matters a lot. Going sword and shield and blocking most attacks is way easier than solely relying on your dodge. The latter is more fun and you won't need a shield down the line but I consider shields to be the training wheels of the series, because you can observe new encounters in relative safety with your shield up.
Any kind of spell, be it pyromancy or classic sorcery trivialises a lot of the enemies, since it's kinda balanced around melee and just hanging back and spamming spell projectiles is easy to do.
So it basically ties the difficulty to the loadout you're choosing which can suck for a new player if he unknowlingly picks a hard loadout but imo gives the game a lot of replayability since different builds play differntly ofc.
If you have regular hand eye coordination, aren't afraid to spend a few minutes learning about how to build your character and have a high tolerance for frustration it is defenitely beatably by everyone.
But you have to judge if you would even enjoy that.
