Do I even NEED to trim my cat's nails? I'm 65 and honestly overwhelmed

Okay I feel silly even asking this here but I'm genuinely confused and need advice from other women my age.

My cat is almost 10, indoor only, has a scratching post she uses all the time. Someone at my daughter's house told me I need to be trimming her nails regularly or they'll grow into her paws?? First I'm hearing of this in 10 years.

Tried looking it up and got a million different answers. Some say the scratching post handles it, some say no it doesn't, some say every 2 weeks, some say only if you hear clicking on the floor.
Honestly even if I do need to do it I don't know how l'a manage.

Is this actually a real thing I need to worry about or am I overthinking it? What do you all do, especially if your hands aren't what they used to be?
