Does Following Tipsters Ruin the Fun for Everyone?

[Player101]

Last week, I watched a movie (Two for the Money) about a gifted former American football player who provides paid predictions for pro and college leagues. At the beginning, he was accurate, but once he became popular and a bunch of players started believing in him, he lost his spark and made many people lose big fortunes.
This is why I prefer to play without taking someone as an idol or reference. Whether I win or lose, I never look for an excuse. If I follow someone else’s predictions, I simply lose the fun behind gambling (Tbh sometimes I use Ai for stats, but it's not the same thing)
What about you? Do you have any names/influencers in mind whose picks are 90% correct (any sport)? Do they really exist? 
Off topic: If you haven’t watched Two for the Money, I recommend it, you’ll really enjoy it

Tailing someone else's picks would ruin most of the fun for me.  I like breaking down matchups and making my own gambling decisions.

Anyone who claims even close to 90% is having a laugh or snake oil salesman or delusional beginner (been there).

Thanks for the movie recommendation!
