Will I get locked out of my Samsung galaxy j3 if I haven't disabled frp lock?

My brother recently got a Samsung galaxy j3, he signed into his Google account and then switched his phone off. When he tried to switch it on again, he couldn't get in so it took 3 hours for the people at the phone place to fix it

So now that I've bought a j3, will I experience the same problem if I sign in with my Google account?

(Sorry if it's a stupid question )

Thank you!
