Everything is very relative and a lot depends on how much you can earn in this way and at what limits) On micro limits there are many players who play only premium
hands and they have a positive ROI%, although they win less than players who have bluffs and play more hands. In general, a person can be trained to play the simplest strategies like a machine, and it is not necessary to have some incredible intelligence. I myself am a person with an average statistical IQ, but at my microlimits I play better than 90% of the field of participants.
But of course players with more intelligence will have an advantage, it's just my opinion that this is not the main factor in being a successful poker player. Working with a coach, finding mistakes and then correcting them will help you play better than most amateurs who just like to look at color cards
