Are soccer fees/expenses tax deductible if the club is registered as a non-profit?

I read something on a face book soccer group where one of the parents was saying that they deduct their soccer expenses. Most folks said that uncle Sam was going to come knocking on their door. I see articles like this on the internet (https://www.beechmontsoccerclub.com...-fees-tax-deductible-maximizing-your-savings/) where they say it is but I'm still highly skeptical. Any tax professionals or parents on here that can chime in? Thanks!
