Why don't my guitar sound good?

I got a 1000 dollar pedalboard Over 1500 dollars worth of pedals and a
6000 dollar guitar Why don't my guitar sound like the pro's my amp's
not great could that be it. it's a crate amp it cost like $300

I can't play that good but it should still sound good when i strum the
guitar. it's not the guitar that sounds bad it's the effects
