Yes, but it's complicated. There are several classes of verb with different endings, and conjugation can depend not just on person and number, but gender.
"Lubić" is a second-conjugation verb, so in the present tense its conjugation is "lubię, lubisz, lubi" in the singular and "lubimy, lubicie, lubią" in the plural. (Luckily, gender doesn't matter here in the present tense)
