Yes. But you shouldn't take it as the only determinant of whether or not you want to play on a site.

A site with a very convoluted and draconian T&C may not enforce it in practice, and it may be okay that you play on their site. Meanwhile, another site with a very simple T&C may actually be a landmine waiting to be stepped on, and actually enforce KYC on all of its customer accounts.

This is very reputation is probably a bit more important than the T&Cs alone, imo. Anyone can cherrypick conditions when it comes to it, but reputation usually indicates whether or not they actually do that in the first place.
