The line from the waterguyboatthing specifies "man", which makes it very unlikely that this was aimed at the player - gender ambiguity is so darn rampant in Undertale. I doubt that gender specificity would occur on the player when Toby knows guys are girls and other will play his game.

MysteryMan is not Gaster's sprite. It is more likely that Gaster's sprite is the one from the room that has "redacted" written in Web Dings. I'll link it here, though it's tiny.

I'm gonna say unlikely, though I've entertained the idea in the past. ^^
