This is a great question and unfortunately the answer is quite complicate !

There are many elements that will determine how you sound, your choice of picks / plucking the strings, the gauge of strings you like to use, the guitar wood / design /pickups, the cables you use, the amp, your choice of tubes, your choice of speakers / material the cab is made form, however sales people know this and constantly use it to sell us "magic solutions" to what ever tonal problems we may present.

I think the biggest single determinant of tone is the way you play i.e. the way you touch / mute, bend and pluck strings.

So in short, yep a nice amp will help you sound better but it is no substitution for a thousand hours playing ! New pickups or a new guitar will also make a difference but again, the way you play will be the thing that makes other people stop and listen.

Yes, ask a way and we will do our best to help out !
