in my experience of ju jitsu (japanese rather than brazilian), the bigger guys guys tend to rely on their strength rather than the technique. but i wouldn't let that you stop you, ju jitsu is good fun!

it has also really helped with my kata understanding.
I'd say it's not just ju jitsu where bigger guys tend to rely on strength - you can see it anywhere, even to the point where (physically) weaker people become instructors and teach that way even though they can only make it work if the "attacker" in a demo attacks in the right way.
