confused with odds!!

[prowannabie]

need a little help here please.I'm not very good with odds so this is probably a stupid question but here it goes.
Example
KK vs JJ
I know everyone says that the jacks are a 4:1 underdog,

is it the same to say that the kings are a 4:1 favorite
or is it actually .25:1?

Thanks for ur help, and feel free to make fun of me, lol
