USA 101 Dumps noob

[j44z]

Hello all,
Very new to carding, but I'm glued to my computer trying to learn as much as possible. I am thinking of doing some instore carding , but just have some quick questions.
I'm in the US , are 101's common? Nearly all my own credit cards have chips. Wouldn't 101's be dead since most cards expire 3-4 years after you get them and chips came out roughly 3-4 years ago.
Should i be focusing on learning to use 201's? Right now I don't really know anything about EMV.
And so if I decide to buy some 101 dumps, from my state, encode them onto plastic, use embosser, go to store, will i be fine?
Not trying to go there and not know/expect something I should.
