Can capital one credit take my car I own and my land I own for non payment of credit cards

if they win the lawsuit, they will obtain a judgment against you and can collect on it through various means, including auctioning off your non-exempt assets.  I do not know what assets are exempt in Texas, but if the land you own is your primary residence, it is probably exempt.  Also, some states (again, i don't know if this is true in Texas) exempt cars, at least to some extent.
