Thank you.
Ok - so outs are when your under...
Makes sense...

And the charts were pretty easy to memorize roughly aswell
on the turn approx 4 * #outs
on the river approx 2 * #outs

And the charts tell you the chance percentage of one card showing up that fulfills your an out.
And that is then related to the potsize/expected win ...
something like, if the pot odds give me 35% I need to have a expected pot of (at least) about 3 times the bet.

Have I gotten it right?

EDIT: ehh, related to potsize or win ?
