We present measurements of the average thermal Sunyaev Zel'dovich (tSZ) effect from optically selected galaxy groups and clusters at high signal-to-noise (up to $12\ensuremath{\sigma}$) and estimate their baryon content within a ${2.1}^{\ensuremath{'}}$ radius aperture. Sources from the Sloan Digital Sky Survey Baryon Oscillation Spectroscopic Survey DR15 catalog overlap with 3,700 sq deg of sky observed by the Atacama Cosmology Telescope (ACT) from 2008 to 2018 at 150 and 98 GHz (ACT DR5), and 2,089 sq deg of internal linear combination component-separated maps combining ACT and Planck data (ACT DR4). The corresponding optical depths $\overline{\ensuremath{\tau}}$, which depend on the baryon content of the halos, are estimated using results from cosmological hydrodynamic simulations assuming an active galactic nuclei feedback radiative cooling model. We estimate the mean mass of the halos in multiple luminosity bins, and compare the tSZ-based $\overline{\ensuremath{\tau}}$ estimates to theoretical predictions of the baryon content for a Navarro-Frenk-White profile. We do the same for $\overline{\ensuremath{\tau}}$ estimates extracted from fits to pairwise baryon momentum measurements of the kinematic Sunyaev-Zel'dovich effect (kSZ) for the same dataset obtained in a companion paper. We find that the $\overline{\ensuremath{\tau}}$ estimates from the tSZ measurements in this work and the kSZ measurements in the companion paper agree within $1\ensuremath{\sigma}$ for two out of the three disjoint luminosity bins studied, while they differ by $2--3\ensuremath{\sigma}$ in the highest luminosity bin. The optical depth estimates account for one-third to all of the theoretically predicted baryon content in the halos across luminosity bins. Potential systematic uncertainties are discussed. The tSZ and kSZ measurements provide a step toward empirical Compton-$\overline{y}\ensuremath{-}\overline{\ensuremath{\tau}}$ relationships to provide new tests of cluster formation and evolution models.
