I will tell you, 100%--with few and far in-between exceptions. If you sit down at a baccarat table in a B&M Casino without some kind of plan--you will probably some where between 99.0 and 100% chance, give back any and all winnings along with your buy-in(s) as well before the night is over.
Take it for granted, tell yourself my words are unfounded and you are stronger than anything that can and will happen at any unintelligent baccarat table in a B&M casino, etc. Go ahead, no problem.
But if you are interested in keeping the casinos money when and if it comes to you, you better have some kind of plan. A plan can be changed-altered and/or expanded upon. But no plan is the worst plan of any type, mark my words. Been there and down all that.
